Even subclassing like
class SpecialString < String
  include SpecialModule
end
?

It seems to me that this is the best of both worlds.

True.  I hadn't considered singleton module inclusion as completely as I 
should have.

How can it be documented?  In the example I gave above, the rdoc for 
SpecialString will say that it includes SpecialModule.  I don't see how 
to do that with a singleton mixin.

> I'm not seeing the minuses.

Start with the lack of documentation.

Also, I admit that something feels deeply *wrong* to me about extending 
individual objects (on more than an occasional basis) without changing 
their nominal class.  I think a class is still a useful construct, but 
too much singleton manipulation renders it meaningless -- a class seems 
to me like a rule for how an object will act, and singleton manipulation 
creates too many exceptions to the rules.  That feels like sloppy, 
unstructured programming to me, although I'll be interested to try the
