Ah, so simple. I missed it because it is not listed in the "formatting
traits" list in the documentation.
This would solve half my problem - I'd no longer need to use {:x} but use
the simpler {}, which is great. Thanks!
But it wouldn't solve the problem for printing enums, though. I guess I'd
still have to litter my code with lots of .to_str() when printing them :-(
