Making a new Mix-in is kinda against "less class (module this case)
policy".  Besides, a Mix-in only mixable to Method or UnboundMethod is
not useful for users anyway.

But, the idea of making Method and UnboundMethod independent itself is
very interesting.  In [ruby-core:00944], Michael disagreed this idea,
but it is very rare to polymorphize (right word?) UnboundMethod and
Method.  They are very different in nature, just like class and its
instance.
