* [3.10] bpo-46581: Propagate private vars via _GenericAlias.copy_with ↵Matt Bogosian2022-03-111-7/+6
| | | | | | | | | | | | | | | | | (GH-31061) (GH-31821) (Cherry-picked from 32bf3597922ac3f613989582afa2bff43bea8a2f.) GH-26091 added the _typevar_types and _paramspec_tvars instance variables to _GenericAlias. However, they were not propagated consistently. This commit addresses the most prominent deficiency identified in bpo-46581 (namely their absence from _GenericAlias.copy_with), but there could be others.

* [3.10] bpo-46333: Honor `module` parameter in ForwardRef (GH-30536) (GH-31379)Miss Islington (bot)2022-02-171-2/+3
| | | | | | | | | | | | | | | The `module` parameter carries semantic information about the forward ref. Forward refs are different if they refer to different module even if they have the same name. This affects the `__eq__`, `__repr__` and `__hash__` methods.

* bpo-46539: Pass status of special typeforms to forward references (GH-30926)Miss Islington (bot)2022-01-271-3/+3
| | | | | | | | | | | Previously this didn't matter because there weren't any valid code paths that could trigger a type check with a special form, but after the bug fix for `Annotated` wrapping special forms it's now possible to annotate something like `Annotated['ClassVar[int]', (3, 4)]`. This change would also be needed for proposed future changes, such as allowing `ClassVar` and `Final` to nest each other in dataclasses.
