Postfix ++ operator overload

Is this some kind of coercive rule that a function overload ++should accept an argument intas a difference from prefix operators?

Also, in the case of a overload ++function prefix , how is the right operand an implicit argument?

For instance, ++ClassObj //ClassObj is rhs, but usualy lhs is made implicit
