How big is the Python Family (py.checkio.org)

Same problem in here.

From the (at least somewhat) active projects Nuitka, a Python to C compiler seems missing here.

This is missing PyonR, which is Python as a Racket #lang.

On the flip side, I'm not sure that PythonNet should count, as it "uses a standard CPython runtime".
