Raymond noticed that that capability seemed nice to have.
So nice in fact that I'm sure I've reimplemented something similar several times. :)
What do you think about reviving this type as general purpose type in collections or types? Perhaps it can be convenient for working with JSON, plists, configuration files, databases and in other cases that need a dict with string keys.
If reintroduce it, there are open questions.
The name of the type.
The location of the type. collections or types? Or other variants?
How it will collaborate with OrderedDict, defaultdict, etc?
Should it be a dict subclass, or a mixin, or a proxy? Or add several
I also wonder whether PEP 557 dataclasses could provide this except in the opposite direction, e.g. by optionally adding __getitem__ support.
This was discussed in https://github.com/ericvsmith/dataclasses/issues/21 and it was decided to postpone this.
