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.)
