Either you make them separate operators (in which case there's no guarantee they do the same thing - see for example Python, where they commonly differ)

Geez. That's obnoxious. Why do we programmers do this to ourselves?

or you are overallocating in the common case.

I see. I was thinking along the lines of being able to use complex numbers with arithmetic operators, not along the lines of doing high performance crunching of floats.
