[Numpy-discussion] var bias reason?

Some colleagues noticed that var uses biased formula's by default in numpy,
searching for the reason only brought up:

http://article.gmane.org/gmane.comp.python.numeric.general/12438/match=var+bias

which I totally agree with, but there was no response? Any reason for this? Is
there any way I can hide the var/std methods of numpy arrays? I have my own
library which does things the R way, and in my lab letting people discover
this 'bug' using name completion in ipython is a nightmare.

Any help?

thanks, Gabriel
