Well my package manager just reported something like 800K for numpy and
20M for scipy, so I think we're not quite at the point of numpy taking
over everything yet (if those numbers are actually meaningful, probably
I'm missing something ?).

I would also welcome if some functionality could be moved to numpy if
the size requirements are reasonably small. Currently I try to avoid to
depend on the scipy package to make my programs more portable, and I'm
mostly successful, but not always. The p-value stuff in numpy would be
helpful here, as Alan already said. Now I don't know if that stuff
passes the size criterion, some expert would know that. But if it does,
it would be nice if you could consider moving it over eventually.

Of course you need to strike a balance, and the optimum is debatable.
But again, if scipy is really more than 20 times the size of numpy, and
some frequently used things are not in numpy, is there really an urgent
need to freeze numpy's set of functionality?

just a user's thought,
