Thank you for this hint.  I wasn't aware of that.

I would be absolutely fine with making the PBP recommendations the
default.   By now, the book is 13 years old and some of its content
is no longer generally accepted - but as far as I can say, the
indentation rules haven't seen any criticism.  And though Damian is
a vim wizard, his book lists the Emacs variables which match his
recommendations - and it is still available for download from
O'Reilly.

Different indentation styles seem to be also present in perl-mode, but
only in the mode's documentation - there's no command to switch all
variables which customize indentation in one go.  Since the set of
available options is different anyway, I guess I can get away with
adding the new option to cperl-mode only.
