Having spent a lot more time playing with MethodHandles and imagining 
the potential, I must say I strongly agree with Fredrik. In the face of 
compiler systems like LLVM and to a lesser extent the CLR/DLR's 
expression tree support, I believe in order for the JVM to survive as a 
dominant platform we *must* give the keys to the castle to language 
developers, by opening up the very guts of the JVM's optimizing 
pipeline. This is the "hole" in the JVM's Java-only exterior that we've 
all been waiting for; an opportunity to finally tell the JVM what we 
really mean rather than always using bytecode as our lingua franca.

Very exciting times ahead.
