[Numpy-discussion] comments on r_ and c_ ?

When you have a chance, could the powers that be make some comment on the r_ and c_ situation? From what I understand Travis added these fairly recently and they aren't officially documented anywhere. There was discussion previously about whether to rename them or not, but no real conclusion was reached on better names (I've kind of grown to like the x_ style naming in the mean time). I do think the subtle differences in behavior between these and existing methods (hstack,vstack,column_stack) are an issue, though, which I outlined in a previous email. Thanks, --Bill
