We are getting off-topic here but I disagree. It is useful to the
programmer or maintainer to see the argument structure at a glance
(especially when writing a lot of functional-style code). It could
even be useful to code analysis tools, though with Perl that's going
to be a bit hard. I think the language syntax is more regular with
this feature than without.

I have found cperl-mode's defaults rather unpleasant and I don't want
to spend ages customising it to my taste (i.e., make it look like
perl-mode). I just use perl-mode and I will be happy if I can fix the
few issues I have with it.
