I disagree completely.  I do a lot of number crunching in
Python where I want IEEE NaN and Inf behavior.  Speed is a
completely orthogonal issue.

Even if you are worried about speed, using tools like like
numpy can do some pretty cool stuff.

Frankly, I don't see that speed has anything to do with it at
all.  I use Python for number-crunching because it's easy to
program in.  When people complain about not getting the right
results, replying with "if you want something fast, don't use
Python" makes no sense.
