ENH: Harmonize drop and rename API (original) (raw)

rename accepts a columns argument or an index argument, while drop looks for a labels and axis pair. I don't know about anyone else, but I have to check the help file every time I come back to pandas to remember which takes which.

How would people feel about adding columns and index arguments to drop? They could just be added in addition to labels/axis if we want to provide backwards compatibility and just raise an exception if the user tries to mix them.
