Perhaps it is worth to mention here that I've always liked to have a sort() 
and argsort() functionality merged in one shot function (or method). Having 
both separated implies two sorts, while if I'd have such a combo available, 
the resulting operation would take quite less time.

One can easily stablish kind of a pattern for situations where this could 
happen: in all the 'arg*()' functions. Perhaps I'm wrong in my count, but 
there appear to be only three of such functions in NumPy, namely, argmax, 
argmin and argsort. Adding three additional 'combos' doesn't seem a lot to my 
mind, but it can be just 'too much' for more common sense minds.

Cheers,
