Maybe I misunderstand the proposal, but, actually, I think this is 
completely the wrong semantics for "axis="  anyway. "axis=" in numpy 
refers to what is also a dimension,  not a  column.

More generally, then, would we restrict this to labeling only the 
column  dimension, or could it be used for any dimension?
