Hmm, the difficulty of creating out parameters was somewhat intentional.
While you might want the capability in a "thin" interface if the
underlying C interface happens to use out parameters, we'd generally
like to encourage people to use a more Perlistic approach of returning
multiple values.

An interesting parallel is that I intentionally wrote rn's Pnews script
in shell so it would run slowly.

Yes, that would be good.

I just wish the average C api was as well specified (and as inspectable)
as the average Java api.  With Java one can write all the glue code
automatically.  (In fact, that's precisely what JPL does.)
