I left a message in the site comment area.

This tutorial is the worst document I have read in a very long time.

Shame on you. If you don't know zit about Perl, have the decency of shutting up, instead of becoming a laughing stock.
See reasons here: http://www.perlmonks.org/?node_id=642535

And this is the answer I got.

Thanks for pointing out this problem to me. I'll see that these problems get fixed, as that site you linked to contained a great deal of criticism that will definitely make Tizag's Perl tutorial a better resource.
I'm not sure what you meant when you said "instead of becoming a laughing stock" but I'm guessing it's along the lines of "you suck". Tizag wasn't written by one person, but your criticism seems well founded and will be addressed.
Thanks,
Brian
