The author of the Perl Circus describes itself nicely:
This site is about Perl. Its not actually about circuses but I definitely think a good Perl coder is a lot like a circus performer — somewhere between a contortionist and a trainer of wild beasts. And I mean that in a good way!
To categorize this site under “Resource Filled” is to understate its value. There are alot of good examples and snipppets here. So visit, learn, discuss, code … not necessarily in that order.
