Well, to say the truth none of both ;-). The truth is that I was trying to=
=20
accelerate some parts of my software and realized that numarray was an=20
important bottleneck. NumPy was already in advanced beta stage and some sma=
ll=20
benchmarks conviced me that it would be the solution. So, I started porting=
=20
one single C extension (PyTables has several), the simplest one, and checke=
d=20
that the results were correct (and confirmed that the new code was much=20
faster!). After that, the second extension came converted and I'm in the=20
process of checking everything. Now, there remains 3 more extensions to=20
migrate, but the important ones for me are done.

So, no plans other than having a good motivation (and the need for speed wa=
s a=20
very good one). However, I think that having a complete test suite checking=
=20
every detail of your software was key. Also, having access to the excellent=
=20
book by Travis was extremely helpful. Finally, having IPython opened to che=
ck=20
everything, look at online docstrings and be able to do fast timings added=
=20
the "cerise sur le g=E2teau".

Luck!
