This seems super-internal, even for Internals. It's already here, so I guess I
won't demand it be changed now, but I'd at least prefer a string, so we won't
have layout tests breaking everywhere if we ever reorder the enumerators.

Done. Will change it above in a follow up CL to not clutter this change with
other layout test fixes.
