I have never found myself missing it in languages that don't support it, nor
using it in languages that do.
I _DO_ use what is technically multiple inheritance in C++ when I inherit
from "pure virtual" classes --
essentially the same as Java interfaces.

Inheritance in general is should be viewed as an implementation convenience
rather than the core of your design (i.e., the interface of MOB is more
important than how any particular specialization is coded).
