--- Comment #1 from Denis Shelomovskij <verylonglogin.reg at gmail.com> ---
Also note this syntax is already used by mistake [1] probably because of recent
compiler changes rejecting meaningless `const`/`immutable` attributes.

Also this currently compiles too because of Issue 13064:
---
auto enum void f();
---
