Personally, I don't like this at all for the following reasons: 1. This introduces two _.. names instead of one. 2.

Hmm, I cannot find the relevant thread, but I thought this was rejected at some point.  Personally, I don't like this at all for the following reasons:

1. This introduces two _.. names instead of one.

2. This departs from established convention that C (or native) implementation for modulename is in _modulename, not _cmodulename.  Non-C implementations may still provide native _modulename, but would not want to call it _cmodulename.

3. Hiding python code in _pymodule makes it harder to find it.

Because this requires having two modules in the first place.
