Ok. But we must keep all doors open by expressing things abstractedly, like
defining classes for C function description. By default, in the "no-op
down-translation" obtained by running the Python-in-Python code over CPython,
the actual calls are implemented with ctypes.
Everything that forces a particular down-translation is bad, even if that
particular down-translation seems good. I can think of other cases where we
will need a description of C function signatures but not the code that
actually call them, e.g. Psyco (for which it will be useful to have some other
information as well, like "does the C function have side-effects").
