I think it is fair to say that Methods are first class, but ruby has  
no first class Method dictionaries. I would LOVE to have real method  
dicts like Smalltalk.

:method returns a copy of the method requested, but it is first class  
just the same. From c2.com:

"A language construct is said to be a FirstClass value in that  
language when there are no restrictions on how it can be created and  
used: when the construct can be treated as a value without  
restrictions."

I think methods in ruby fit that (for the most part).
