+     * Any clause function may neglect to take any trailing subsequence of parameters it is entitled to take.
+     * In fact, any clause function may take no arguments at all.

+     * init function is automatically a loop parameter {@code a}.)

+     * 
          
+     * 
        • Given {@code N} clauses {@code Cn = {null, Sn, Pn}} with {@code n = 1..N}.
+     * 
        • Suppose predicate handles {@code Pn} are either {@code null} or have no parameters.
+     * (Only one {@code Pn} has to be non-{@code null}.)
+     * 
        • Suppose step handles {@code Sn} have signatures {@code (B1..BX)Rn}, for some constant {@code X>=N}.
+     * 
        • Suppose {@code Q} is the count of non-void types {@code Rn}, and {@code (V1...VQ)} is the sequence of those types.
+     * 
        • It must be that {@code Vn == Bn} for {@code n = 1..min(X,Q)}.
+     * 
        • The parameter types {@code Vn} will be interpreted as loop-local state elements {@code (V...)}.
+     * 
        • Any remaining types {@code BQ+1..BX} (if {@code Q
+     * In this example, the loop handle parameters {@code (A...)} were derived from the step functions,
+     * which is natural if most of the loop computation happens in the steps.  For some loops,
+     * the burden of computation might be heaviest in the pred functions, and so the pred functions
+     * might need to accept the loop parameter values.  For loops with complex exit logic, the fini
+     * functions might need to accept loop parameters, and likewise for loops with complex entry logic,
+     * where the init functions will need the extra parameters.  For such reasons, the rules for
+     * determining these parameters are as symmetric as possible, across all clause parts.
+     * In general, the loop parameters function as common invariant values across the whole
+     * loop, while the iteration variables function as common variant values, or (if there is
+     * no step function) as internal loop invariant temporaries.
+     * 
          
      * Loop execution.

          1. When the loop is called, the loop input values are saved in locals, to be passed (as the common suffix) to
+     * 
          2. When the loop is called, the loop input values are saved in locals, to be passed to
      * every clause function. These locals are loop invariant.
-     * 
          3. Each init function is executed in clause order (passing the common suffix) and the non-{@code void} values
-     * are saved (as the common prefix) into locals. These locals are loop varying (unless their steps are identity
-     * functions, as noted above).
-     * 
          4. All function executions (except init functions) will be passed the common parameter sequence, consisting of
-     * the non-{@code void} iteration values (in clause order) and then the loop inputs (in argument order).
+     * 
          5. Each init function is executed in clause order (passing the external arguments {@code (a...)})
+     * and the non-{@code void} values are saved (as the iteration variables {@code (v...)}) into locals.
+     * These locals will be loop varying (unless their steps behave as identity functions, as noted above).
+     * 
          6. All function executions (except init functions) will be passed the internal parameter list, consisting of
+     * the non-{@code void} iteration values {@code (v...)} (in clause order) and then the loop inputs {@code (a...)}
+     * (in argument order).
      * 
          7. The step and pred functions are then executed, in clause order (step before pred), until a pred function
      * returns {@code false}.
-     * 
          8. The non-{@code void} result from a step function call is used to update the corresponding loop variable. The
-     * updated value is immediately visible to all subsequent function calls.
+     * 
          9. The non-{@code void} result from a step function call is used to update the corresponding value in the
+     * sequence {@code (v...)} of loop variables.
+     * The updated value is immediately visible to all subsequent function calls.
      * 
          10. If a pred function returns {@code false}, the corresponding fini function is called, and the resulting value
-     * is returned from the loop as a whole.
+     * (of type {@code R}) is returned from the loop as a whole.
+     * 
          11. If all the pred functions always return true, no fini function is ever invoked, and the loop cannot exit
+     * except by throwing an exception.
      * 
          
      * 
          
-     * Here is pseudocode for the resulting loop handle. In the code, {@code V}/{@code v} represent the types / values
-     * of loop variables; {@code A}/{@code a}, those of arguments passed to the resulting loop; and {@code R}, the
-     * result types of finalizers as well as of the resulting loop.
+     * Usage tips.
+     * 
            
+     * 
          • Although each step function will receive the current values of all the loop variables,
+     * sometimes a step function only needs to observe the current value of its own variable.
+     * In that case, the step function may need to explicitly {@linkplain #dropArguments drop all preceding loop variables}.
+     * This will require mentioning their types, in an expression like {@code dropArguments(step, 0, V0.class, ...)}.
+     * 
          • Loop variables are not required to vary; they can be loop invariant.  A clause can create
+     * a loop invariant by a suitable init function with no step, pred, or fini function.  This may be
+     * useful to "wire" an incoming loop argument into the step or pred function of an adjacent loop variable.
+     * 
          • If some of the clause functions are virtual methods on an instance, the instance
+     * itself can be conveniently placed in an initial invariant loop "variable", using an initial clause
+     * like {@code new MethodHandle[]{identity(ObjType.class)}}.  In that case, the instance reference
+     * will be the first iteration variable value, and it will be easy to use virtual
+     * methods as clause parts, since all of them will take a leading instance reference matching that value.
+     * 
          
+     * 
          
+     * Here is pseudocode for the resulting loop handle. As above, {@code V} and {@code v} represent the types
+     * and values of loop variables; {@code A} and {@code a} represent arguments passed to the whole loop;
+     * and {@code R} is the common result type of all finalizers as well as of the resulting loop.

+     * (In the {@code void} case, we assign the type {@code void} to the name {@code V},

     /**
-     * Constructs a loop that ranges over the elements produced by an {@code Iterator}.
-     * The iterator will be produced by the evaluation of the {@code iterator} handle.
-     * This handle must have {@link java.util.Iterator} as its return type.
-     * If this handle is passed as {@code null} the method {@link Iterable#iterator} will be used instead,
-     * and will be applied to a leading argument of the loop handle.
-     * Each value produced by the iterator is passed to the {@code body}, which must accept an initial {@code T} parameter.
-     * The result of the loop execution is the final value of the additional local state
-     * obtained by running {@code init}.
+     * Constructs a loop that ranges over the values produced by an {@code Iterator}.
+     * This is a convenience wrapper for the {@linkplain #loop(MethodHandle[][]) generic loop combinator}.
      * 
    
-     * This is a convenience wrapper for the
-     * {@linkplain MethodHandles#loop(MethodHandle[][]) generic loop combinator}, and the constraints imposed on the {@code body}
-     * handle follow directly from those described for the latter.
+     * The iterator itself will be determined by the evaluation of the {@code iterator} handle.
+     * Each value it produces will be stored in a loop iteration variable of type {@code T}.
+     * 
    
+     * If the {@code body} handle returns a non-{@code void} type {@code V}, a leading loop iteration variable
+     * of that type is also present.  This variable is initialized using the optional {@code init} handle,
+     * or to the {@linkplain #empty default value} of type {@code V} if that handle is {@code null}.
+     * 
    
+     * In each iteration, the iteration variables are passed to an invocation of the {@code body} handle.
+     * A non-{@code void} value returned from the body (of type {@code V}) updates the leading
+     * iteration variable.
+     * The result of the loop handle execution will be the final {@code V} value of that variable
+     * (or {@code void} if there is no {@code V} variable).
+     * 
    
+     * The following rules hold for the argument handles:
      
+     * 
    • The {@code body} handle must not be {@code null}; its type must be of the form
+     * {@code (V T A...)V}, where {@code V} is non-{@code void}, or else {@code (T A...)void}.
+     * (In the {@code void} case, we assign the type {@code void} to the name {@code V},
+     * and we will write {@code (V T A...)V} with the understanding that a {@code void} type {@code V}
+     * is quietly dropped from the parameter list, leaving {@code (T A...)V}.)
+     * 
    • The parameter list {@code (V T A...)} of the body contributes to a list
+     * of types called the internal parameter list.
+     * It will constrain the parameter lists of the other loop parts.
+     * 
    • As a special case, if the body contributes only {@code V} and {@code T} types,
+     * with no additional {@code A} types, then the internal parameter list is extended by
+     * the argument types {@code A...} of the {@code iterator} handle; if it is {@code null} the
+     * single type {@code Iterable} is added and constitutes the {@code A...} list.
+     * 
    • If the iteration variable types {@code (V T)} are dropped from the internal parameter list, the resulting shorter
+     * list {@code (A...)} is called the external parameter list.
+     * 
    • The body return type {@code V}, if non-{@code void}, determines the type of an
+     * additional state variable of the loop.
+     * The body must both accept a leading parameter and return a value of this type {@code V}.
+     * 
    • If {@code init} is non-{@code null}, it must have return type {@code V}.
+     * Its parameter list (of some form {@code (A*)}) must be
+     * effectively identical
+     * to the external parameter list {@code (A...)}.
+     * 
    • If {@code init} is {@code null}, the loop variable will be initialized to its
+     * {@linkplain #empty default value}.
+     * 
    • If the {@code iterator} handle is non-{@code null}, it must have the return
+     * type {@code java.util.Iterator} or a subtype thereof.
+     * The iterator it produces when the loop is executed will be assumed
+     * to yield values which can be converted to type {@code T}.
+     * 
    • The parameter list of an {@code iterator} that is non-{@code null} (of some form {@code (A*)}) must be
+     * effectively identical to the external parameter list {@code (A...)}.
+     * 
    • If {@code iterator} is {@code null} it defaults to a method handle which behaves
+     * like {@link java.lang.Iterable#iterator()}.  In that case, the internal parameter list
+     * {@code (V T A...)} must have at least one {@code A} type, and the default iterator
+     * handle parameter is adjusted to accept the leading {@code A} type, as if by
+     * the {@link MethodHandle#asType asType} conversion method.
+     * The leading {@code A} type must be {@code Iterable} or a subtype thereof, or an array type.
+     * This conversion step, done at loop construction time, must not throw a {@code WrongMethodTypeException}.
+     * 
    
+     * 
    
+     * The type {@code T} may be either a primitive or reference.
+     * Since type {@code Iterator} is erased in the method handle representation to the raw type {@code Iterator},
+     * the {@code iteratedLoop} combinator adjusts the leading argument type for {@code body} to {@code Object}
+     * as if by the {@link MethodHandle#asType asType} conversion method.
+     * Therefore, if an iterator of the wrong type appears as the loop is executed, runtime exceptions may occur
+     * as the result of dynamic conversions performed by {@link MethodHandle#asType(MethodType)}.
+     * 
    
+     * The resulting loop handle's result type and parameter signature are determined as follows:
      
+     * 
    • The loop handle's result type is the result type {@code V} of the body.
+     * 
    • The loop handle's parameter types are the types {@code (A...)},
+     * from the external parameter list.
+     * 
    
      * 
    
      * Here is pseudocode for the resulting loop handle. In the code, {@code V}/{@code v} represent the type / value of
      * the loop variable as well as the result type of the loop; {@code T}/{@code t}, that of the elements of the
-     * structure the loop iterates over, and {@code A}/{@code a}, that of the argument passed to the loop.
+     * structure the loop iterates over, and {@code A...}/{@code a...} represent arguments passed to the loop.
      * 
    {@code
-     * Iterator iterator(A);  // defaults to Iterable::iterator
-     * V init(A);
-     * V body(T,V,A);
-     * V iteratedLoop(A a) {
-     *   Iterator it = iterator(a);
-     *   V v = init(a);
+     * Iterator iterator(A...);  // defaults to Iterable::iterator
+     * V init(A...);
+     * V body(V,T,A...);
+     * V iteratedLoop(A... a...) {
+     *   Iterator it = iterator(a...);
+     *   V v = init(a...);
      *   for (T t : it) {
-     *     v = body(t, v, a);
+     *     v = body(v, t, a...);
      *   }
      *   return v;
      * }
      * }
    
      * 
    
-     * The type {@code T} may be either a primitive or reference.
-     * Since type {@code Iterator} is erased in the method handle representation to the raw type
-     * {@code Iterator}, the {@code iteratedLoop} combinator adjusts the leading argument type for {@code body}
-     * to {@code Object} as if by the {@link MethodHandle#asType asType} conversion method.
-     * Therefore, if an iterator of the wrong type appears as the loop is executed,
-     * runtime exceptions may occur as the result of dynamic conversions performed by {@code asType}.
-     * 
    
      * @apiNote Example:
      * 
    {@code
-     * // reverse a list
-     * static List reverseStep(String e, List r, List l) {
+     * // get an iterator from a list
+     * static List reverseStep(List r, String e) {
      *   r.add(0, e);
      *   return r;

-     * static List newArrayList(List l) { return new ArrayList<>(); }
