Classes represent objects that contain state. Classes have
initialization; modules don't contain state (as such).

If I were to have:

  class A; def initialize @foo = 1; end; end
  class B; def initialize @foo = 2; end; include A; end

What would the result be?

If you need to "include" a class into another class, use composition
and delegation, IMO:

  class C
    def initialize @a = A.new; end
    def method_missing(s, *a, &b); @a.__send__(s, a, b); end
  end
