The 0th entry of the PADLIST is a PADNAMELIST (which is actually just an
AV, but that may change) which represents the "names" or rather
the "static type information" for lexicals. The individual elements of a
-PADNAMELIST are PADNAMEs (just SVs; but, again, that may change).
+PADNAMELIST are PADNAMEs (just SVs; but, again, that may change). Future
+refactorings might stop the PADNAMELIST from being stored in the PADLIST's
+array, so don't rely on it. See L<PADLIST_NAMES>.
The CvDEPTH'th entry of a PADLIST is a PAD (an AV) which is the stack frame
at that depth of recursion into the CV. The 0th slot of a frame AV is an
