Pinning the return type to Num is bad e.g. if you want multi targets

If at all possible, I would expect Complex to compose Num, thus
letting a Complex be used anyw
I think I found the core of the issue here; it has to do with the
differences between roles and mixins, with an analogous difference
between compile-time composition and runtime composition. Details
follow.

I thought about doing it that way; but then the class wouldn't know to
look for it when composing the role.
I figure you see the class in a very active role when composing ro

Just to make sure we're speaking the same language: by "superclass",
you're referring to classes brought in via "is";
