best way to study it is to read it in conjunction with poking at Perl
source, and we'll do that later on.
-You might also want to look at Gisle Aas's illustrated perlguts -
-there's no guarantee that this will be absolutely up-to-date with the
-latest documentation in the Perl core, but the fundamentals will be
-right. ( http://gisle.aas.no/perl/illguts/ )
+Gisle Aas's illustrated perlguts (aka: illguts) is wonderful, although
+a little out of date wrt some size details; the various SV structures
+have since been reworked for smaller memory footprint. The
+fundamentals are right however, and the pictures are very helpful.
