The Design Pattern motto is "If you're using multiple inheritance,
you're designing your class hierarchy badly". As a guiding principle,
it's always served me well. Like an infinite quantity in an equation,
it's a sure sign of a need to renormalise.

Isn't it interesting, though, that the languages with multiple
inheritance are those that seem to lead to *least* code reuse?
