Well, the f2py as included in numpy is at least stable, since it has
been used with little to no change for scipy the last few years, whereas
fwrap is largely untested on the scale of something like scipy. I was
suggesting to look into fwrap *if* f2py would be really hard to make to
work for python 3.x.
What worries me for f2py is not so much the python code (at worst, we
could hack something to call f2py through python 2.x for the 3.x build -
numscons runs f2py out of process for // build) as much as the generated
C code. Debugging code generators is rarely fun in my experience :)
