i mean it's meaning is the similar to 'attr :a == trait :a'.

but are the other traits being used?  also these seem to be called roles in
some langs too...  this is a valid concern though.

what do you think could be more natural than

   class C
     has 'a' => 42
   end

   c = C::new
   p c.a       #=> 42

or

   class AbstractWidget
     class << self
       has 'color'
       has 'width'
       has 'height'
     end
   end

   class SmallishBlueWidget
     color 'blue'
     width 100
     height 42
   end

??

it's the best i could manage.  come up with something more natural and i'll
see what i can do to implement.

i'm working 70+ hours per week already - but if someone wants to take over and
do the initial setup work it's fine with me.

this is welcome of course - but see above.

+1 for attributes then.

cheers.
