[Numpy-discussion] alter_code1.py changes .stddev() to .std() ...

I'm having a lot of fun converting python code from numarray to numpy 
and I just found out that the alter_code1.py conversion script changes 
numarray's '.stddev()' to numpy's '.std()', even though the semantics 
are different ("sample" std.dev. or not; divide by N-1 vs. by N).

Should I open yet another ticket about '.std()'?

This will be easy to solve once .std() has a parameter to choose the 
divisor, but what is everybody using in the mean time?
