Given that the
FrozenListtype hint isUnion[List[_T], Iterable[_T]]the Application middleware type should not restrict to
Sequenceandsupport all
Iterabletypes.What do these changes do?
In my application I pass a generator type as the middleware argument to create a web.Application. mypy complains that it is not a
Sequencetype as hinted in the class. I feel the Sequence hint isto restrictive and an Iterable is the better choice.
Are there changes in behavior for the user?
No.
