Perl is seen as a complicated language. Which is true.
I disagree. Perl people like to think Perl is complicated but in reality, it's an extremely easy to learn language. The documentation is second to none, there are many great sources of help, and the language itself is very logical and easy to follow, even if it does look like line noise ;-P
As for being included with a OS at Walmart, it means nothing and won't increase the user base substantially. I applaud you for bring it up though, discussion of Perl advocacy is a good thing :)
