The controversial Ref class I made a while back on this list has this 
property, I think, with the exception that it also has a deref property 
which allows you to assign it a different delegate-object. You could remove 
that interface, but I imagine it could be handy.
It just uses Delegate, and redefines is_a?, kind_of?, respond_to, and 
Module#===.
