Seriously, why all the extra complexity for something you'll never care about?

You don't care about the exact contents of __repr__ as long as it's
predictable.  You don't really care about item iteration order either as long
as it's defined.  Sorting by attribute name fulfills both use cases *and* it's
simple.  Zen 3 FTW.
