---END CONSOLE TEXT--- I'm thinking we should fork the whole lib directory into pypy and have the interpreter's pythonpath point there. I'm trying to get the pure-python bytecode compiler package in order. The python distribution already goes 80% of the way. I've got a plugin replacement for parser.pyd. But where do I stick it so it's found before the pyd? I also want to write a interim version of tokenizer.py. The current version uses regexes. This is the way we should ultimately do it, but a pure python DFA would be nice while dependancies are being worked out (although slow as hell). I could just drop that in the lib directory, but then we're running against a patched version of CPython. The only other alternative is to insert something into pythonpath before any of the standard entries so we can stub stuff in there. Still, if the ultimate goal is to have a standalone pypy interpreter, we're going to need to fork sooner or later. Sooner will allow us to flush out some unanticipated dependancies in the early stages. Of course the downside of doing this is that someone will need to monitor CPython's lib directory and port patches across. It might be a little time consuming, but for now the patches on python-commit should be able to be applied easily.
