--- Comment #3 from Iain Buclaw <ibuclaw at gdcproject dot org> ---
Introduced upstream by:

https://github.com/dlang/dmd/pull/15664


Before:
---
enum `object.Foo` enum `Foo` must have at least one member
---

After:
---
enum `object.Foo enum `Foo` must have at least one member
---

There's no coverage from the upstream D2 testsuite either it seems.
