Error in stub files: Variables are not allowed in type expressions

The stub files use a call to type to get the NoneType.

NoneType = type(None)  # incorrect

This is not allowed in type expressions. The correct way should be as follows:

type NoneType = type[None]  # since Python 3.12
NoneType: TypeAlias = type[None]  # pre Python 3.12

I came across this error in QtCore.pyi and QtWidgets.pyi but it probably affects other stub files too.
