I think with the new fancy constants you can put the bootstrap
method(handle) in the constant pool and the invokedynamic instruction
refers to the constant pool; no registering required.

Can't you put many lisp functions in one class file?  At least for
non-closure functions that seems possible.

Reflection is never cheap, at least according to folk wisdom.
