Ugh.  Doesn't Perl provide some saner way to determine the type of a SV?

The core code seems to think that SvOK() is a sufficient test for an
undef.  Should we be doing that before the switch, perhaps?

(My underlying concern here is mostly about whether we have other
similar bugs.  There are a lot of places checking SvTYPE.)
