in c++ if you overload ++ you distinguish the postfix version by giving it a dummy int parameter, which to my knowledge is pretty much only there so the compiler can tell the difference

I think it's just a rule to differentiate them for the compiler.  I don't know of any logical reason why they made it that way and not the other way around, although I could be mistaken.
