ok, done.

close, instead let's output multiple inputs as a YAML stream, with each 
having their own document:

   module Kernel
       def y( *x )
           puts( if x.length == 1
                     YAML::dump( *x )
                 else
                     YAML::dump_stream( *x )
                 end )
       end
       private :y
   end

works the same, but allows Kernel#y to dump headless documents if only 
one input is sent.

great suggestions, cool, cool...
