I'm not convinced that is indeed the best  approach. So Uri expects
either a plain string, or a scalar ref to a string.

What if instead you get an object? Do you want to treat it as a scalar
ref, or as a plain string? IMO you *don't* want to peer inside the
intestines of an object, instead, you ought to treat the object as a
black box, *not* look at what kind of blessed ref it is, and thus, you
should be wanting to use the stringified object.

Thus: treat only an unblessed scalar ref as a scalar ref.
