not sure where the statement "all over again" comes from, given that the
tech we use for CPython-bindings pre-dates Cython by half a decade or more.
Now it's just being re-used and re-implemented for PyPy in a way that fits
PyPy best.

That'd be great, but we (HEP) absolutely need C++ in all it's ugly glory,
and it needs to be fully automatic from the header files. W/o that ability,
which we do have today for CPython, there would be no Python in HEP. This
discussion seems to be mostly restricted to C.

Best regards,
