Circular references in perlguts

perlguts has this very unhelpful text:

"svtype  An enum of flags for Perl types.  These are found in the file 
sv.h in the "svtype" enum.  Test these flags with the "SvTYPE" macro.

"SVt_IV  Integer type flag for scalars.  See "svtype".
SVt_NV  Double type flag for scalars.  See "svtype".
SVt_PV  Pointer type flag for scalars.  See "svtype".
SVt_PVAV Type flag for arrays.  See "svtype".
SVt_PVCV Type flag for code refs.  See "svtype".
SVt_PVHV Type flag for hashes.  See "svtype".
SVt_PVMG Type flag for blessed scalars.  See "svtype"."

This is useless for telling me anything.  It would be nice if someone 
who knew what they were doing would properly document these flags.
