Also type hints for dictionaries with fixed keys:

I know it's almost always better to use objects for this, but tons of code still uses dictionaries as pseudo-objects. This should make bug hunting a lot easier.

Huh, was totally unaware of this. For me this has good implications for ingesting CSVs/.xlsx to dicts. Clean-ups / type hinting is required at times for dirtier documents.

Oh, nice! I'll have to add that to json-syntax.[1]
