Using DictProxy.values() yields false positives #8814
Description
If I run mypy with the following code:
from multiprocessing.managers import DictProxy
from multiprocessing import Manager
d: DictProxy[str, float] = Manager().dict()
d["hallo"] = 4.2
d["test"] = 2.8
print(sum(d.values()))
It should give no typing errors, as the values of DictProxy should be an Iterable[float]. Instead however, i receive error: Argument 1 to "sum" has incompatible type "List[Tuple[str, float]]"; expected "Iterable[bool]" for line 9 (the print-line)
Is this an issue with typeshed or more with the python multiprocessing-library?
