The other thing this patch is missing are tests, btw.

I think that `operator++()` and `operator--()` should be handled as well as
the assignment operators. @rsmith, thoughts?


I agree; if we're going to assume that overloaded operators are intended to
mutate the object in the cases where the builtin form does, that should
apply to all such operators -- assignment, compound assignment, increment
and decrement.
