Hi.

Features available in PyPy (or Java or IronPython) are not language features.
These are features are available through normal python syntax, just
some libraries
are available extra. Python is something that passes most of CPython's test
suite, modulo stuff that is considered implementation detail (like
reference counting).
In fact, some of extra PyPy features can be achieved via extension modules like
greenlets.

Cython might as well at some point become one, but so far it does not even
import the whole test suite (correct me if I'm wrong), hence it's not
yet python.

Even if the ultimate goal is to support whole Python, it's not
achieved yet, so it
should not be considered implementation of Python (as of today, it might as well
be one tomorrow).

Cheers,
fijal
