--- Comment #1 from Simon Naarmann <eiderdaus at gmail.com> ---
Right, this has nothing to do with Nullable in particular. This warning
appeared in my existing codebase after I switched from DMD 2.083.2 to 2.084.0,
and the codebase doesn't use Nullable.

The workaround is to remove the 'alias this' in S.

But it's very common to wrap class references in structs and then alias-this to
the class. Would love to see a quick fix!
