A number of attempts have been made to address this problem
over the years; for example, Simon Cozens once set up a
(now defunct) "code review ladder".
At that time, there were more folks wanting reviews
than prepared to do them, presumably
because performing a detailed, quality code review
is very time consuming and few people have the time
and inclination to do it.
You might try posting some of your code to the latest attempt at such a site, namely
However, before doing that, I suggest you
isolate small pieces of code
that you're unhappy with and post multiple
small questions here to the Seekers of Perl Wisdom section.
That way, you will surely get a quick response
which you can use to improve and polish your code
before submitting to PrePAN, say (if PrePAN is
appropriate for your code, which we would be able
to advise on).
