Please stop using the plural. There is precisely one function whose axis 
default gets overridden in this manner, and that is cumsum(). Given that 
there are unittests for it, I can only assume that the override is 
deliberate and chosen with the Numeric incompatibility in mind.

You can still disagree about that decision, but please constrain your 
comments to the specifics: namely, that you think cumsum()'s axis 
argument should default to 0.

My position is that cumsum() should remain as it is, but it and all 
other changes to Numeric's behaviours should be documented. To that end, 
I've started a wiki page.
