Great list, Coping with Scoping reminded me of Suffering from Buffering... one thing I have to watch out for though is this is (so far) a single sticky thread... although, I could do as the CSS guys did where it did indeed end up a multipage sticky. However many many many more people come to SitePoint asking the same CSS questions over and over again so that makes sense. Since there's maybe one person in the Programming Team with any experience with Perl, I'm probably not going to expect them to pare down what I've got.
However I think these and some of the other tuts can hopefully completely replace the current "Articles and Tutorials" Section... means I may not have to worry about how good those are if I can replace with a list like yours of Known Good Stuff. I've added the general link to Tuts over here and to planetscape's list of links as well.
