I don't know if the native typing stuff is "more advanced" than our
current code or not; that's kind of fuzzy terminology if you think
about it. It is, however, a lot different than what we do in the
existing PL/python, or, to the best of my knowledge, any of the other
PLs with, perhaps, the exception of PL/pgsql. So conceivably someone
could submit a PL/perlNG, a PL/lolcodeNG, etc. taking a similar
approach. It's worth thinking about how we feel about that.
