This is not a bug report, but a feature request.  If I understand
correctly, both go through the same channel.

Motivation: cperl-mode offers a command 'cperl-set-style' which sets
some customization values for code formatting according to a list of
rule sets.  The book "Perl Best Practices", known as "PBP" in the Perl
community, also defines such a rule set, including the corresponding
settings for Emacs (among other editors).

The PBP rules are widely accepted for Perl code, so in my opinion it
makes sense to make these settings available through 'cperl-set-style'.

The attached patch adds the new value "PBP" to the style selection and
to the documentation, and also contains a simple formatting test
according to these rules.

I also added some lines to etc/NEWS, but I'm unsure about the handling
of "---" to indicate that the change is not relevant to the manual:
There is no texinfo manual for CPerl mode, so maybe "---" should be
added before the heading "CPerl Mode"?
