@MoonlightSentinel created dlang/phobos pull request #7760 "Make
isAutoDecodableString independent of issue 21570" mentioning this issue:

- Make isAutoDecodableString independent of issue 21570

  The current implementation relies on issue 21570 to reject enums with
  static arrays as their base type.

  Use another is-expression instead of `isStaticArray` to detect types
  that are (convertible to) static arrays.
