I'm experimenting with the implementation of a Smalltalk-like language.
I'm using invokedynamic that targets a trivial stub that dispatches over
the receiver's type which finally invokes a DMH.

A simple test shows a factor of 150-200 with respect to an ordinary
invokevirtual. That is, my Smalltalkish method invocation
implementation, although seemingly trivial, is about 2 orders of
magnitudes slower than Java's :-( That's why I'm wondering if inlining
is at work.
