If dictionary order is not guaranteed in the spec and the dictionary order isn't randomized (which I think everyone agrees is a bit messed up), it would probably be useful if you could enable "random order mode" in CPython, so you can stress-test that your code isn't making any assumptions about dictionary ordering without having to use an implementation where order isn't deterministic.

As has been suggested elsewhere, if we decide not to make that guarantee, then we should probably deliberately randomize iteration order.
