There are a number of suites in the Monastery that provide this sort of information:

• Seekers of Perl Wisdom: questions people have asked and answers they have received.
• Tutorials: Introductory (and not so introductory) materials covering Perl and Perl idioms, and much more
• Snippets Section: snippets of code that solve specific problems in an interesting or elegant fashion
• Cool Uses For Perl: full blown (by generally small) Perl solutions to various problems that demonstrate cool ways to do stuff with Perl
• Code Catacombs: large scale Perl applications and modules that solve high level problems using Perl
• Categorized Questions and Answers: a FAQ sorted by category with in depth answers to questions covering many different areas of Perl use

I don't think that adding yet another wing to the building is going to make the trail to find an answer to any particular question any shorter. A good way to save shoe leather and search all the material here is to use super search. Super search is your friend!
