--- Comment #1 from Dlang Bot <dlang-bot at dlang.rocks> ---
@MoonlightSentinel created dlang/dmd pull request #13804 "alias parameters"
fixing this issue:

- Fix 22871 - Support aliases to __traits(parameters).

  The current implementation had two bugs preventing users from using
  the tuple returned by `__traits(parameters)` bound to an alias:

  - the parser rejected `typeof(__traits(X))`, i.e. a traits without
    parameters. Fixed by removing the check for existing arguments.
  - type semantic rejected the alias as invalid and eagerly issued an
    error. Fixed by extending the list of viable traits.
