[issue46399] Addition of `mapping` attribute to dict views classes has inadvertently broken type-checkers

[Guido van Rossum]

Guido van Rossum <guido at python.org> added the comment:

(Though since this can only work for 3.11+,
maybe typeshed could also be adjusted?
For that you’d have to file a bug there.)
