AFAIK, the main argument is that this would allow for easier
transition, since someone could use 2to3 to make the transition from
numpy for python 2 to numpy for python 3. But is it even possible for
a large package like numpy ? I don't see how the C api for example
could be backward compatible, since the API with PyString and PyInt
would have to be changed.
I guess time will tell, once other package with a lof of C will be
converted. I am curious to see whether this advice from the python dev
community will be followed at all.
