One reason I encouraged this project is that it is synergistic with
other optimizations in the pipeline, namely using ConstantDynamic
(condy) to translate non-capturing lambdas and method refs. This has a
direct performance benefit (lighter than indy) and offers more sharing.
Further, a little farther down the road is more aggresive constant
propagation, which may turn some capturing lambdas into non-capturing
ones (big win already), and further expose them to condy-ization and
