* Adapters which mediate between incoming calls which are generic
* and outgoing calls which are not. Any call can be represented generically
* boxing up its arguments, and (on return) unboxing the return value.
* <p>
* A call is "generic" (in MethodHandle terms) if its MethodType features
* only Object arguments. A non-generic call therefore features
* primitives and/or reference types other than Object.
* An adapter has types for its incoming and outgoing calls.
* The incoming call type is simply determined by the adapter's type
* (the MethodType it presents to callers). The outgoing call type
* is determined by the adapter's target (a MethodHandle that the adapter
* either binds internally or else takes as a leading argument).
* (To stretch the term, adapter-like method handles may have multiple
* targets or be polymorphic across multiple call types.)
