though this only works with the attribute type methods provided by traits:

   harp:~ > cat a.rb
   require 'traits'

   trait 'foo' => true

   puts( foo ? 'foo' : 'not foo' )
   puts( foo? ? 'foo' : 'not foo' )

   foo false

   puts( foo ? 'foo' : 'not foo' )
   puts( foo? ? 'foo' : 'not foo' )


   harp:~ > ruby a.rb
   foo
   foo
   not foo
   not foo

cheers.
