--- Comment #5 from Dennis <dkorpel at live.nl> ---
I know this issue was first, but 21868 already got a pull.

It is the same problem: `return scope` without `ref return` applies return the
values (e.g. SSOString.raw.ptr), not the address of SSOString itself (e.g.
SSOString.small.data.ptr), but the compiler doesn't check for return-scope or
return-ref, just return. The declaration of `Raw raw` is needed because
otherwise SSOString has no pointers, so return scope is stripped away, so the
compiler can't mistake the return attribute anymore and raises the correct
error.
