That's also my general observation:  When I need composite objects, I
practically always find that I also need operations on them beyond any
simple model that could reasonably be supported directly via language
operators.  Complex multiplication is just one of the simplest examples.
Since I have to provide a set of explicitly programmed operations anyway,
it is not a lot of additional bother that the language doesn't directly
support a few of them.
