Is this significantly different from the coroutine example in
the PiL book  <http://www.lua.org/pil/9.2.html> that goes
something like:

consumer( filter ( producer() ) )

Don't get me wrong, I like pipes, I'm just not seeing how
the piping you're proposing is anything more than syntactic
sugar for the above code...
