Um, yes, any two strings have an ordering, if you assign values to
their symbols. But we're not *using* the ordering, that's the
important thing.

(The fact that we use ordering trivially as part of the process of
generating a new unique ID is irrelevant. Call it the "next" key is
misleading: it's just a "new" key, and the method by which we
guarantee its uniqueness doesn't need to infect the rest of the code.)

Nah, calling it FUD is FUD :-). My statement was personal, and
completely accurate. If it's not true for you, that's great -- I
never said it was.
