How stable is that link? I fell into the trap of using references to the Perl docs on perldoc.org for a while as they were more up to date than those on PM, but it was a mistake. Initially, the site was fine, but after a short while it became flacky, spending more time down than up. And then it simply disappeared.
Of course, if it was possible to produce properly indexed HTML using pod, we be able to link directly to the section of perlop entitled "Equality operators", which would be a significant improvement. But that ain't gonna happen anytime soon.
