|The problem this solves is very real-world. Consider a Perl class hierarchy in which a class Child inherits from classes Mother and Father:
Uh, oh. Multiple Inheritance.
A couple of years of doing Smalltalk (which didn't have multiple inheritance, but which let you fake interface interitance via mixins), and a couple of years of Java and C++ have lead me to believe that Multiple Inheritance is a Very Risky Thing, and that it can always be worked around by either composition or reducing to inheriting from one data-bearing class and multiple (data-less) interface classes. Doing so avoids the multiple destructor problem.
Perhaps you've run into a situation where multiple inheritance is the right thing to do. If so, I'd like to hear about it.
