Is it possible to reflect the text of a dynamically generated method  
definition?

I'm debugging some ActiveRecord code and it would be very helpful to  
dump the text of some of the generated methods.  For example, say I  
have this:

class Foo < ActiveRecord::Base
   has_one :bar
end

AR associations generates a whole host of methods, Foo#bar,  
Foo#create_bar, etc., and the exact definitions depend on the options  
that I passed to has_one.  I can walk through associations.rb and  
friends to reconstruct what I think the methods look like but that is  
slow and error prone.

There must be an easier way, this is Ruby after all!

Thanks,
