To go with my recent post on Perl testing, here's the BBC's Perl Programming Style Guide: Appendix A. Perl Coding Standards It is a lighweight guide (doesn't impose variable naming schemes and such like) but useful nevertheless. Interestingly doesn't mention taint checking for CGI code that I would have thought would be a must. Nevertheless a good starting point (and it is a draft version v0.14). Thanks to the Dublin Perl Mongers' list for alerting me to this one.
