I realized while working on srittau/type-stub-pep#64 that a
few things we do in existing enum definitions in typeshed are
problematic:
- Using "= ..." doesn't allow type checkers to correctly type the
result of Enum.MEMBER.value. In fact, mypy at least infers
.value to be "Ellipsis" if you do this.
- Properties on the enum values themselves, like HTTPStatus.phrase,
should not be specified directly as attributes, because it makes
type checkers think that the properties themselves are enum
members.
I ended up doing a bit more cleanup to the signal module:
- Remove unnecessary ... initializers.
- Remove unnecessary _SIG = Signals alias.
- I don't have Windows to test, but the C code for _signal suggests
that CTRL_C_EVENT and CTRL_BREAK events are not Signals, but just ints:

The stub for asyncio.as_completed declared it as taking a Sequence of
Futures. This was unnecessarily strict.
Just like asyncio.wait, asyncio.as_completed can be declared to take
an Iterable of Futures instead. Both these functions iterate over
their argument only once to store its items in a set, so an Iterable
is sufficiently strict. This has been true since the initial
implementation of the functions.
This takes advantage of a recent mypy change to respect the return
type of `__new__`. Using that it does the same tedious overloads
as `run` and `check_output`.
This gives better types to `subprocess.check_output` and `subprocess.run`
by laboriously overloading using literals.
To support `run`, I turned `CompletedProcess` into `_CompletedProcess[T]`
with `CompletedProcess = _CompletedProcess[Any]`. I could pretty easily
be convinced that it would be better to just make `CompletedProcess`
generic, though.
I'd like to do the same for Popen but need to make mypy support
believing the type of `__new__` in order for that to work.
Both are None if there were no groups matched. Also 'lastgroup'
will be None if the matched group was nameless.
The Python 2 versions of these annotations already used Optional.
* Add types and functions in types.py that are new in 3.7
* Update `resolve_bases` to accept any iterable of objects, and the same
for `new_class` if the version is at least 3.7
* Add comparison overrides implemented by MethodWrapperType
* Fix mypy error due to over-constrained `__eq__`
Morsel does cast any value to string and therfor any is the correct
typehint. For some keys other types then strings are more
appropiate anyway, max-age can take an integer (unix time) and http-only
a boolean.
Closes#3059
This includes two things to sync up with recent runtime updates:
* Move `Final`, `@final`, `Literal`, and `TypedDict` to `typing` (`typing_extensions` still defines or re-exports them)
* Rename `@typing.runtime` to `@typing.runtime_checkable`, while keeping `@runtime` as a backwards-compatible alias in `typing_extensions`.
