I'll take a look at PyPy. However, it's likely we will use our existing naive compiler as the basis for the PBC compiler, since it works within the context of our Antlr grammar, including supporting infrastructure like incremental parses, as well as some other scaffolding like scopes compilation.

Then I can (again) suggest that you look at PyPy instead of rewriting
your own .pyc compiler from scratch -- but that might not be quite what
you are looking for, given that (as I understand it) writing PBC would
be mostly an extension of your own Python-to-Java compiler.
Nevertheless, I'm sure that if you want to try that path, you can try to
extract code from PyPy, and plug it in Jython either in the form of pure
Python code or compiled Java code.
