I believe that ix_() has recently begun modifying the shapes of its
input arrays. For instance:
Python 2.4.4c0 (#2, Jul 30 2006, 18:20:12)
[GCC 4.1.2 20060715 (prerelease) (Debian 4.1.1-9)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as N

argmin is currently defined as using the argmax method!
>From numpy/oldnumeric/functions.py
def argmin(x, axis=-1):
return N.argmax(x, axis)

+1 for float64 for me as well.

I agree. As are sinh, cosh, tanh, sinc, exp, log10 and various
other very commonly used (and not only in programming) names.
lstsq, eig, irefft, etc are not.

I'll add my 2 cents to this and agree with David. Arguments
about how short name are important for interactive work are pretty
bogus given the beauty of modern tab-completion. And I'm not sure
what other arguments there are...
