And clearly neither has anyone else, hence the absence from the
stdlib. As others have pointed out, there are alternative approaches,
and plenty of recipes on ActiveState, which seem to have scratched
whatever itch there is for the data structure you're advocating.

While Python's motto is "batteries included" I've always felt there
was an implicit "but not the kitchen sink" following it. Just because
something "could" be useful shouldn't be grounds for inclusion. That's
what pypi & the recipes are for. Ideally, little should be created
wholesale for the stdlib, what should be added are the existing 3rd
party modules that have become so ubiquitous that their presence on
any python platform is just expected.
