Since $plain's not a fixed scalar type, it should be whatever the
division of $c and $d produces, presumably a complex number.

I prefer letting the destination decide, with automatic type changing
as the default. Given the potentially large number of variable types
that can be created, I can't picture a workable hierarchy that won't
be restrictive here.

That's an interesting idea. I kind of like it--float it past Larry
and p6-language and see what happens.
