Me either.
I think we need to take this more slowly. Frankly, I think we have most
of what we really wanted already, and I suspect anything else is
probably not worth the code complexity involved. The original motivation
as I understood it was to enable people to embed a piece of pl/foo in a
script with minimal syntactic overhead, and I think that's been achieved.
