Oh, ratzafratz: I forgot which newsgroup I was in. The *Java*
language has access to this sort of information via reflection.
Still, the information is very nearly read-only, and reflection
can't inject a new enum into the mix. (Java can, of course, load
a new .class with a new definition for the enum -- but that just
introduces a different enum class that happens to have the same
name, under the scope of a different classloader.)
