Subject: Is there some way to execute a block within an arbitrary lexical scope?

Is there some way to execute a block within a certain lexical scope?

Let's say the scope I want is inside B:
module A
  class B
    # .. wanna get in here
  end
end

And I wanted something like:

method_returning_B_in_lexical_scope_of_A.class_eval do
   ...
end

As most of you know 'A::B.class_eval' does not cut it, since A would not 
be in the nesting.

The obvious reason I want this is to take advantage of the nesting for 
lookups.

Thanks for any ideas!
