I've bookmarked your index for future use. What I've been using up til now is
http://search.cpan.org/dist/perl/pod/perl.pod, taking the links to perlfunc
http://search.cpan.org/~nwclark/perl-5.8.7/pod/perlfunc.pod or perlvar
http://search.cpan.org/~nwclark/perl-5.8.7/pod/perlvar.pod. From there I can just do a find for the items I'm looking for.
