I follow you now.

My plan so far is going to be to, for every distinct type-altenum
pair, generate a set of constants named from the name of the type and
the names of the enum elements.

So with either plan I would be generating sets of typed constant named:

windowNone, atomNone, timecoordNone, etc.

The names aren't as fully qualified as they properly should be,
though.  But unless I uncover any name-clashes in practice, I'll be
generating the same costants for either patch.
