Well, I disagree with prohibiting nested methods.

What do you mean?  When I try it, a nested method is scoped so that it 
is only visible inside the method it's defined in.  That's exactly the 
behavior you want for nested methods to be useful.

Seems to me that define_method is for creating and redefining methods 
dynamically, which is an orthogonal problem. Then again, I've never used 
it or seen it used, so I may be misunderstanding what it's for. 
"Programming Ruby" doesn't seem to have any detail on what it's for or 
why you'd want to use it.
