Cython is great, but I question that it is a *Python* implementation. 
That's not a criticism of Cython, but it is different from Python. Take 
this example code from the tutorial:

from libc.math cimport sin

cdef double f(double x):
    return sin(x*x)

If that's Python code, then I'm Ethel the Aardvark.

Cython is very Python-like, but there is no doubt in my mind that it is a 
superset of Python and therefore a different language.
