Subject: Creating modules


I am dynamically creating modules [1]. I would like to be able to add
methods and constants to the module using the "normal" notation:

module MyModule
  def a_method; 'wibble'; end
end

But the module doesn't have an constant associated with it, so I'm
getting an error from...

class MyModuleClass < Module
  def initialize(a_constant_to_go_in_module)
    module self
      K = a_constant_to_go_in_module
      def a_method; end
      ...
    end
  end
end

Is there a way to do this, or do I have to start using the define_method
and const_set methods?

Cheers,

[1] These modules encapulate the behaviour of different types of
message. There are quite a few types of message; while all different,
they're sufficiently similar that the differences can be described in a
table. It's easy to think of a class of types of message: a given
message is an instance of a type of message.
