Sounds like we're pretty much reaching consensus. Phew.

Oh, I do tell myself that :-). With my committer/consensus-building hat on,
np.ma has users, so I want something they can live with, and was suggesting
some options. For myself I don't really care what np.ma does though since I
don't use it...

Grammatically, fill_with is an imperative, which suggests it needs an array
to operate on; it's synonymous with just plain 'fill'. Having 'fill' and
'fill_with' as different functions with different semantics would be pretty
