@TungstenHeart created dlang/dmd pull request #12329 "fix 21756 - make
`cast(immutable)arrayLiteral` @nogc" fixing this issue:

- fix 21756 - make `cast(immutable)arrayLiteral` @nogc

  adjust array literal semantics so that

  ```d
  cast(immutable) <arrayLiteral>
  ```

  gets rewritten to a DeclExp comma VarExp

  ```d
  (static immutable __array = <arrayLiteral>, __array)
  ```

  allowing immutable array literals to be `@nogc`
