I'm worried primarily about interactions with the expression parser,
which changes for every language we support.  I don't know if the test
coverage is adequate or not.

Definitely.  I don't suggest removing anything here.

It may be so.  My tentative plan was to offer a selection, probably
Perl and Python and Guile; once the common infrastructure is in place,
it's really not hard to add languages and enable them at configure
time.  The alternative would be to add only Guile, since that's the
language the FSF officially recommends for such things - I don't want
to take that alternative, though, since I'm practically useless in
Guile.  I have implemented Guile embedding, by the way, though never
finished it up.

Just musing, for the moment.
