Back in school, we learned a language that allowed this sort of thing.
It may have been the language "Clu", from MIT, but I am not sure.

I don't know about C++, but Ada certainly does have this ability:
you simply define a function something like this:

	function "\" (in x, y:integer) returns integer is begin ... end;

modulo my rusty syntax.
