I believe one of the things discussed in today's teleconference, and
one that I support, was to add to the syntax for :lang() by allowing
a string to be the argument, so that :lang("*-1996") can be used.

(It's then worth considering exactly which non-identifier cases
should be allowed, and which should require escaping or being
written as strings.)
