Victor Stinner	4a21e57fe5	bpo-40268: Remove unused structmember.h includes (GH-19530) ... If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.	2020-04-15 02:35:41 +02:00
Guido van Rossum	48b069a003	bpo-39481: Implementation for PEP 585 (#18239) ... This implements things like `list[int]`, which returns an object of type `types.GenericAlias`. This object mostly acts as a proxy for `list`, but has attributes `__origin__` and `__args__` that allow recovering the parts (with values `list` and `(int,)`. There is also an approximate notion of type variables; e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`. Type variables are objects of type `typing.TypeVar`.	2020-04-07 09:50:06 -07:00
