That's pypy. pypi is something else. sys.platform is not any good, since for example PyPy, and possibly any other python implementation that is not CPython, but it's not tied to any particular platform (like parrot) would say "linux2" or "win32". sys.implementation sounds good, but it'll also require a list in stdlib what's fine and what's not fine and a flag sounds like something that everyone can set, not asking to be listed in stdlib. How about sys.implementation.supports_extensions?
