Actually, in the particular case of the problem I'm working on now, I 
think I'm going to add in another base class to inherit from, and the 
subclass that doesn't want those methods won't use that base class.

But that approach won't work all the time - is there anything out on 
CPAN that helps with the encapsulate-and-expose approach? Or any design 

Doing things properly is obviously a Good Thing, but it seemed a heck of 
a lot simpler to say "this, minus these" than to go off and add do fun 
stuff with extra encapsulating classes, etc. :)
