That's similar to what I did in Ruby Behaviors, but with an "off"
switch for the non-block version:

   # Block
   b.adopt do
     ...
   end

   # No block
   b.adopt
   ...
   b.desist

(where b is a Behavior object)

Of course, Ruby Behaviors had some issues, especially thread safety --
which is what got the discussion going about selector namespaces at
RubyConf 2001 :-)
