[Numpy-discussion] Py3k and numpy

[Lisandro Dalcin]

>From my experience working on my own projects and Cython:

* the C code making Python C-API calls could be made to
version-agnostic by using preprocessor macros, and even some
compatibility header conditionally included. Perhaps the later would
be the easiest for C-API calls (we have a lot already distilled in
Cython sources). Preprocessor conditionals would still be needed when
filling structs.

* Regarding Python code, I believe the only sane way to go is to make
the 2to3 tool to convert all the 2.x to 3.x code right.

* The all-new buffer interface as implemented in core Py3.0 needs
carefull review and fixes.

* The now-all-strings-are-unicode is going to make some headaches ;-)

* No idea how to deal with the now-all-integers-are-python-longs.
