My experience tells me that lots of subclassing is a bad smell. Delegation 
is often simpler and less fraught with possibility for name conflicts.

Perl's inheritance mechanism is particularly egregious, of course. SUPER 
is broken, and without private methods or attributes of any sort, it's 
really easy to step on your parent's internals and break things.

"All problems in computer science can be solved by another level of 
indirection" (Butler Lampson)

... except the problem of having too many levels of indirection.


Which no doubt you've all heard before, but it's worth remembering.
