Subject: Re: problem with inner classes

I'm curious why you have that many "inner" classes. Mind sharing?

If I had 20 of them and they were substantial enough to deserve their own
files, I think I would have put them inside a module instead of inside a
class. At least in the scenarios I can think of.
