The closest thing is the output of perldoc perlstyle, which I don't think is what you're looking for.

Perl culture seems to be absorbed (or not) by osmosis. And varies widely between people.

As you note, Perl (or at least Larry) tries to appeal to many different programmers with very different backgrounds. A lot of useful work gets done (poorly) in Perl by programmers who haven't yet learned that consistent indentation is A Good Thing. Rather less (due to sheer force of numbers) useful work gets done (generally much better) by very competent programmers who are likely to come to Perl with strong opinions already developed that mostly are going to work out OK.

This contrasts strongly with Smalltalk where (at least at the start) you could assume that anyone coming to Smalltalk was going to have some major unlearning to do first. Having a consistent style be part of the relearning makes sense in that context.

The cognoscenti of Perl would generally be happy if everyone could learn not to use Matt Wright's scripts, and that the language is not called PERL.
