FWIW, I've considered an attr_query that created foo= and foo? methods.

Yesterday I also considered attr_proc that would construct methods like
this:

   obj.doit = proc { do_stuff }   # set the callback
   obj.doit                       # call it!

Of course, this sort of thing is easily doable in Ruby, so I don't see
a core change as appropriate unless this became widespread.
