New error codes:

  • Introduce Y041: Ban redundant numeric unions (int | float, int | complex,
    float | complex).
  • Introduce Y042: Type alias names should use CamelCase rather than snake_case
  • Introduce Y043: Ban type aliases from having names ending with an uppercase "T".
  • Introduce Y044: Discourage unnecessary from __future__ import annotations import.
    Contributed by Torsten Wörtwein.
  • Introduce Y045: Ban returning (Async)Iterable from __(a)iter__ methods.

Other enhancements and behaviour changes:

  • Improve error message for Y026 check.
  • Expand Y026 check. Since version 22.4.0, this has only emitted an error for
    assignments to typing.Literal, typing.Union, and PEP 604 unions. It now also
    emits an error for any subscription on the right-hand side of a simple assignment, as
    well as for assignments to typing.Any and None.
  • Support typing_extensions.overload and typing_extensions.NamedTuple.
  • Slightly expand Y034 to cover the case where a class inheriting from (Async)Iterator
    returns (Async)Iterable from __(a)iter__. These classes should nearly always return
    Self from these methods.
  • Support Python 3.11.
