-1 for any functions added to numpy. As only an end-user, I realize I have little right to a say in these sorts of issues, but for whatever it may be worth, I strongly agree with Gael's viewpoint. We should be aiming towards modular systems for function distribution, and now that it seems that these are being gradually worked out (scikits?), I think we should avoid adding anything to numpy, which should rather be kept to a bare minimum: just the necessaries for array creation and manipulation. Everything else should go in the add-on modules which can be installed as required.
This have the benefit that the numpy package stays well-defined and contained, meaning that end-users know exactly what to expect as available on a given system. Instead of wondering "Where do I find functions for x. I know numpy has some things. Maybe it's in there or maybe somewhere else." I would always know that in order to get functions for x I would install the correct, usefully named, module. This seems like the path of least surprise, and a cleanest interface. I agree it's great that numpy is on the OLPC, and would like to see it accompanied there by a "Basic Functions" module containing, for example, these financial functions, which certainly sound useful... but not for everyone.
