        Good question. I'd submit these operators are also part of their types, only they are part of more than one type at a time.

        In the case of multiplication, something like D&D's hierarchical type system would be interesting, as the multiplication could be deemed part of the number supertype to both real and integer. Too bad it was deemed too complicated and not useful enough for Alphora Dataphor.

        In the case of concatenation, I would submit that it belongs to char, the number of times is just a parameter. But I might be seriously wrong.
