Subject: adding method to existing class

  I need to include some methods in class stored in some variable:

  some_class = Struct.new( 'SomeClass', 'some_field' )
  blah = some_class.new( 'anything' )

  Now I want object blah (and other objects of some_class) to respond
  to method some_method. I've tried to include module with my method
  but I don't like evaling:

  module Feature
         def some_method
         ...
         end
  end
  some_class.class_eval { include Feature }
  blah = some_class.new( 'anything' )

  Now blah responds to some_method. Is there way to include methods
  without eval?
