It seems sad, though, that reftype() won't be patched to XSRETURN_NO, especially as that makes more sense. Also, why can't the Perl version be patched to at least return !!0 instead of explicit undef?

XSRETURN_NO is how you do return !!0 in XS.

And the answer I think is here: 

D:\dev\>perl -e"print defined !!0"

But Im hopeful that the p5p powers that be will be receptive of the idea of a _reftype() sub that returns PL_no instead of Pl_undef. (Which is what XSRETURN_NO and XSRETURN_UNDEF do.)
