Sven is right. We already have the rank() function as a matrix function.
Changing its behaviour if the argument is a series is feasible, but I'm
wondering if the usefulness of rank() for series outweighs or not the
potential confusion that may arise. We probably should leave the decision
to the commander-in-chief (no, not THAT one).
Well, of course the function need not be called "rank()". Call it
"ranking()" or "rankorder()" or whatever. The name is not important
but
what it performs, namely assigning ranks to the values in a series.
