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 PrePAN. 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).
