Will we use GIL or "gil"? It would be great to keep compatibility with
Pyrex here to avoid confusion. But if we rename it's better to have
the same behavior too.

I don't see one change that I submitted to Pyrex and was included in
their release 0.9.6, it's about checking the return of tp->new() for
NULL (exceptions generated in __new__())

http://lists.copyleft.no/pipermail/pyrex/2007-May/002327.html

but you may check if Greg applied as-is or if he did some other checks there.

I haven't tried it or looked at the generated code, but AFAIU the file
where rdef is defined will always use the C version and not this
overriden pure-python subclasses. That's the case? If so, what's the
point in this? (use case)


Last thing: why did you removed callable() as a known built-in?
(http://www.cython.org/hg/cython/rev/28a5fc848c53) Do you plan to add
it back? How about getattr()?
   I know getattr is not being used due the C version using 2
parameters while the python version uses 3, we can have our
Cython_Getattr() as a static inline function that does the check or
add one more element to builtin_functions tuple to check for number of
provided parameters or change this tuple by an object that could have
its methods overriden and in this case it will just work.
