Is there a major objection to just adding in explicit syntax for order-preserving dictionaries? To some extent that seems like a reasonable compromise position in an "explicit is better than implicit" sense. A whole lot of code is out there that doesn't require or expect order-preserving dictionaries - it would be nice to be able to differentiate out the parts where order actually *does* matter.
(Of course, given that CPython's implementation is order-preserving, a bunch of code is probably now being written that implicitly requires on this detail, but at least having syntax that makes that clear would give people the *option* to make the assumption explicit).
