[Python-Dev] Calling Methods from Pythons C API with Keywords

The reason I asked on this in the first place is I had looked through
the python source to make sure PyObject_Call had no equivalent that
supported keywords, and since I needed to do this I figured it might be
worth considering for Pythons API.
Im sure everyone could write their own PyObject_Call, if they had to but
thats what the API's for.

Agree a Python/C API List would be great, in fact I cant see any reasons
not to have it- likely the pure python users dont want to know about
refcounting problems.. etc anyway.
There are lists/newsgroup for py2exe and pyrex, Python-ObjectiveC etc,
Python/C API seems much more generic, and its also fairly tricky to use
at times - when doing more advanced stuff (subtyping has been tricky for
me anyway). I expect the dev's of pyrex, pygame etc might also need to
discuss C API spesific issues as well.
Iv had roughly this conversation in IRC...
Q. Hi, Id like to know how wrap python subtype methods in the C API
A. C dosnt have classes, use C++
Q. no I want to use pythons C API,
A. Subtypes are easy to do in python..
...... you get the idea...
Quite a few "python only" users dont understand where the Python/C API
fits in and its annoying to have to explain the question each time (yes,
Iv had these conversations more then once)
