--- Comment #1 from Bolpat <qs.il.paperinik at gmail.com> ---
This is actually 2 issues:
- If a `case` label is out of range for the `enum` type’s backing type, should
that be illegal? (IMO, yes, except in templates.)

- If a `case` label has a value that’s in range for the type’s backing type,
but is different from all `enum` values, should that be an error? (IMO, hard
no. Some `enum` types are bit-fields and it can make sense to test for certain
combinations specifically.)
