I'm not so sure about returning undef here. Why not fall back to the
default behaviour of Perl 5 without overload q{""} magic? As in, return the
stringified reference.

As Bart Lateur (who I've been meaning to thank for pointing it out, thanks!)
pointed out, the object there -is- stringified; use overload q{""} magic is
called.
So, some method should be provided to avoid the stringification, akin to
overload::StrVal(). Perhaps overload::StrVal is sufficient.
