I honestly don't see this "bias" as being towards Python given the mild contents of the single paragraph where he mentions it. Not to mention this line from the first page: "But nothing is flawless — indeed, not even Perl." Unless that was sarcastic, but it doesn't seem like it to me.

Anyway, it seems to me that whenever Perl gets critiqued, it's the same arguments that get raised (or 'misraised', such as criticisms against implicit variables). It seems like we need a Perl advocacy document (faq, howto, manpage, pod, something), to expand upon the bits of perlfaq1 that address this sort of thing. http://www.perl.org doesn't seem to have this sort of straight-forward doc on hand, just a few points directed towards IT managers.
