Maybe it could, but that's not the point of a programming language. A programming language is for people, not computers, to read. It is whole lot easy to recognise "swap(a,b)" or even "a<->b" as a swapping operation than three lines of code. -- Derek Parnell Melbourne, Australia skype: derek.j.parnell
IMO operator is the best. Otherwise anyone will reinvent the wheel again and again. See C++, there are much of swap functions, and much of nothrowing problem in swap.
