hmm.  i guess here

   def a; 'forty-two'; end

   set_var 'a', 42
   p a

we get the method.  and here

   def a; 'forty-two'; end

   a = 42
   p a

we get the local_variable.  so in either case you get a name clash - but the
sense of it is reversed with set_var.  i wonder if this is un-intuitive enough
to render it useless?

cheers.
