maybe:

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

   trait 'foo' =3D> %w( a b c )

   def mfoo
     foo.each{|f| p f}
   end

   mfoo


   harp:~ > ruby a.rb
   "a"
   "b"
   "c"

or you can write this

   require 'traits'

   trait 'foo'

   foo 42

   def mfoo
     foo.each{|f| p f}
   end

   mfoo

which is kinda close to what you want.

hth.
