Not that long ago Brett, Barry, and I were talking about how to get
extension authors to move away from the C-API. Cython is the obvious
choice, but it isn't an official tool nor does it necessarily make
sense to make it one. Regardless, it would help all parties involved
if there *were* an official tool that was part of CPython (i.e. in the
repo). Cython could build on top of it and extension authors would be
encouraged to use it or Cython. If such a thing makes sense, I figure
we would follow the pattern set by asyncio (relative to twisted).
