...went for this in the end. i suppose the case statement w/ array 
include opt didn't really fit the needs, all in all. thanks all for your 
answers though.

David, what is this all? method? is it a Array#method ? i didn't find it 
in the docs..?

     [*a].all? {|e| include?(a) } and not [*b].any? {|e| include?(e) }
