+ * greeter.setGreeting("howdy");
+ * mh.invoke();  // prints "howdy, world" (object-like mutable behavior)
+ * </pre></blockquote>
+ * <p>
+ * In the example of {@code Greeter}, the method {@code run} provides the entry point.
+ * The entry point need not be a constant value; it may be independently
+ * computed in each call to the constructor.  The entry point does not
+ * even need to be a method on the {@code Greeter} class, though
+ * that is the typical case.
+ * <p>
+ * The entry point may also be provided symbolically, in which case the the
+ * {@code JavaMethodHandle} constructor performs the lookup of the entry point.
+ * This makes it possible to use {@code JavaMethodHandle} to create an anonymous
+ * inner class:
+ * <p><blockquote><pre>
+ * // We can also do this with symbolic names and/or inner classes:
+ * MethodHandles.invoke(new JavaMethodHandle("yow") {
+ *     void yow() { System.out.println("yow, world"); }
+ * });
+ * </pre></blockquote>
+ * <p>
+ * Here is similar lower-level code which works in terms of a bound method handle.
+ * <p><blockquote><pre>
+ *     class Greeter {
  *         public void run() { System.out.println("hello, "+greetee); }
  *         private final String greetee;

- *             this.greetee = greetee;
- *         }
+ *         Greeter(String greetee) { this.greetee = greetee; }
  *         // the entry point function is computed once:
  *         private static final MethodHandle RUN
- *             = MethodHandles.findVirtual(MyMethodHandle.class, "run",
+ *             = MethodHandles.findVirtual(Greeter.class, "run",
  *                   MethodType.make(void.class));

+ *     // class Main { public static void main(String... av) { ...
  *     Greeter greeter = new Greeter("world");

- *     MethodHandle mh = greeter;
+ *     MethodHandle mh = MethodHanndles.insertArgument(Greeter.RUN, 0, greeter);
  *     mh.invoke();  // also prints "hello, world"
  * </pre></blockquote>
+ * Note that the method handle must be separately created as a view on the base object.
+ * This increases footprint, complexity, and dynamic indirections.
+ * <p>
+ * Here is a pure functional value expressed most concisely as an anonymous inner class:
+ * <p><blockquote><pre>
+ *     // class Main { public static void main(String... av) { ...
+ *     final String greetee = "world";
+ *     MethodHandle greeter = new JavaMethodHandle("run") {
+ *         private void run() { System.out.println("hello, "+greetee); }
+ *     }
+ *     greeter.invoke();  // prints "hello, world"
+ * </pre></blockquote>
  * <p>
- * In this example, the method {@code run} provides the entry point.
- * The entry point need not be a constant value; it may be independently
- * computed in each call to the constructor.  The entry point does not
- * even need to be a method on the Java method handle class, though
- * that is the typical case.
+ * Here is an abstract parameterized lvalue, efficiently expressed as a subtype of MethodHandle,
+ * and instantiated as an anonymous class.  The data structure is a handle to 1-D array,
+ * with a specialized index type (long).  It is created by inner class, and uses
+ * signature-polymorphic APIs throughout.
+ * <p><blockquote><pre>
+ *     abstract class AssignableMethodHandle extends JavaMethodHandle {

+     *     (This treatment of interfaces follows the usage of the bytecode verifier.)
+     * <li>If T0 and T1 are primitives, then a Java casting

+     *     A conversion from another primitive type behaves as if

+     *     Otherwise, T0 is boxed, and its wrapper converted to T1.
+     * <li>If T0 is a reference and T1 a primitive, an unboxing

      * <em>PROVISIONAL API, WORK IN PROGRESS:</em>
-     * Adapt a target method handle {@code target} by first processing
-     * its arguments, and then calling the target.
-     * The initial processing is performed by a second method handle, the {@code combiner}.
-     * After this, control passes to the {@code target}, with the same arguments.
+     * Make a method handle which adapts a target method handle,
+     * by running it inside an exception handler.
+     * If the target returns normally, the adapter returns that value.
+     * If an exception matching the specified type is thrown, the fallback
+     * handle is called instead on the exception, plus the original arguments.
      * <p>
-     * The return value of the {@code combiner} is inserted into the argument list
-     * for the {@code target} at the indicated position {@code pos}, if it is non-negative.
-     * Except for this inserted argument (if any), the argument types of
-     * the target {@code target} and the {@code combiner} must be identical.
-     * <p>
-     * (Note that {@link #dropArguments} can be used to remove any arguments
-     * that either the {@code combiner} or {@code target} does not wish to receive.)
-     * <p>
-     * The combiner handle must have the same argument types as the
-     * target handle, but must return {@link MethodHandle} instead of
-     * the ultimate return type.  The returned method handle, in turn,
-     * is required to have exactly the given final method type.
+     * The handler must have leading parameter of {@code exType} or a supertype,
+     * followed by arguments which correspond <em>(how? TBD)</em> to
+     * all the parameters of the target.
+     * The target and handler must return the same type.
      * <p> Here is pseudocode for the resulting adapter:
      * <blockquote><pre>
-     * signature V(A[pos]..., B...);
-     * signature T(A[pos]..., V, B...);
-     * T target(A... a, V v, B... b);
-     * V combiner(A..., B...);
-     * T adapter(A... a, B... b) {
-     *   V v = combiner(a..., b...);
-     *   return target(a..., v, b...);
+     * T target(A...);
+     * T handler(ExType, A...);
+     * T adapter(A... a) {
+     *   try {
+     *     return target(a...);
+     *   } catch (ExType ex) {
+     *     return handler(ex, a...);
+     *   }
      * }
      * </pre></blockquote>
-     * @param target the method handle to invoke after arguments are combined
-     * @param pos where the return value of {@code combiner} is to
-     *          be inserted as an argument to {@code target}
-     * @param combiner method handle to call initially on the incoming arguments
-     * @return method handle which incorporates the specified dispatch logic
-     * @throws IllegalArgumentException if {@code combiner} does not itself
-     *          return either void or the {@code pos}-th argument of {@code target},
-     *          or does not have the same argument types as {@code target}
-     *          (minus the inserted argument)

+     * @param handler method handle to call if a matching exception is thrown
