Imho consistency is not lost there precisely because one can use
ones((5)) if one is so inclined. So the double-parentheses habit (or
call it tuple-habit if you like) goes through. In contrast, rand((5,5))
fails, and that is what breaks consistency.

A "little mind" is an accurate description of myself in the numpy field.
But I believe that in order to become a success, numpy must take into
account the needs of little minds as well.

I was arguing that it's inconvenient exactly because it's inconsistent,
so I don't see the tradeoff here. (Given that I'm fairly indifferent
between one or two pairs of parentheses.)
In any case I promise to shut up about this when 1.0(beta) is out, but I
think Alan is right that under the status quo there will be a constant
stream of the same newbie question that I asked.
cheers,
Sven
