Well, if you do it right, the enclosing code would not be different
from that of a "truly full" implementation. That's why we use objects
in the first place! The rest of the code should need no information
about how you implement your mutable complex type.

So unless there's a performance issue I can't see what you lose by
wrapping the complex number.
