bpo-32873: Remove a name hack for generic aliases in typing module (GH-6376)
This removes a hack and replaces it with a proper
mapping {'list': 'List', 'dict': 'Dict', ...}.

bpo-32873: Treat type variables and special typing forms as immutable by copy and pickle (GH-6216)
This also fixes python/typing#512
This also fixes python/typing#511

As was discussed in both issues, some typing forms deserve to be treated
as immutable by copy and pickle modules, so that:
* copy(X) is X
* deepcopy(X) is X
* loads(dumps(X)) is X  # pickled by reference

This PR adds such behaviour to:
* Type variables
* Special forms like Union, Any, ClassVar
* Unsubscripted generic aliases to containers like List, Mapping, Iterable

This not only resolves inconsistencies mentioned in the issues, but also
improves backwards compatibility with previous versions of Python
(including 3.6).

Note that this requires some dances with __module__ for type variables
(similar to NamedTuple) because the class TypeVar itself is define in typing,
while type variables should get module where they were defined.

bpo-32226: PEP 560: improve typing module (#4906)
This PR re-designs the internal typing API using the new PEP 560 features.
However, there are only few minor changes in the public API.

Łukasz Langa f350a268a7 bpo-28556: typing.get_type_hints: better globalns for classes and modules (#3582)
This makes the default behavior (without specifying `globalns` manually) more
predictable for users, finds the right globalns automatically.

Implementation for classes assumes has a `__module__` attribute and that module
is present in `sys.modules`.  It does this recursively for all bases in the
MRO.  For modules, the implementation just uses their `__dict__` directly.

This is backwards compatible, will just raise fewer exceptions in naive user
code.

Originally implemented and reviewed at https://github.com/python/typing/pull/470.

Guido van Rossum bd5b9a0742 Many changes from the upstream repo (https://github.com/python/typing).
This syncs to rev 7b43ada77821d23e55e3a4b35f6055a59b9e1ad7 there.

Summary:

- Add typing.DefaultDict (as a generic variant of collections.defaultdict).

- Use collections.Reversible if it exists (only relevant for Python 3.6).

- Revamped generic class behavior to conform to updated PEP 484.

- Improve speed of Generic.__new__.

- Make sure __init__ is called for new Generic instances. Fix issue #26391.

- Refactor async support to be compatible with 3.2, 3.3, 3.4.

- Remove 'io' and 're' from __all__ (they still exist, just not
  included by "import *"). Fix issue #26234.

- Change @overload -- you can now use it outside stubs (you still
  cannot call the decorated function though).

Guido van Rossum 46dbb7d103 Preliminary typing.py, anticipating provisional acceptance of PEP 484.
There area bunch of TODOs here, but the biggest (not mentioned in the
file) is that I'm going to take out __instancecheck__ and
__subclasscheck__.  However my personal schedule is such that I
probably won't have time for these before Larry tags beta 1.  But I
will try -- this commit is mostly to make sure that typing.py doesn't
completely miss the train.

PS. I'm tracking issues at https://github.com/ambv/typehinting/issues.
