--- Comment #2 from Dlang Bot <dlang-bot at dlang.rocks> ---
@MoonlightSentinel created dlang/dmd pull request #13135 "Issue 22004 - Allow
noreturn returns from void functions" mentioning this issue:

- Issue 22004 - Allow noreturn returns from void functions

  This is valid because
  - noreturn is convertible to any type (incl. void)
  - the program will abort/throw while evaluating the expression and hence
    never actually return a value

  This means that the ReturnStatement` can be replaced by the standalone
  expression without changing the behaviour of the program.

  ---

  Doesn't fix 22004 because the supplied example requires further changes
  to accomodate for `return <noreturn>;` and subsequent `return;`'s.
