A secure coding standard for the Perl programming language can create the highest value for the longest period of time by focusing on the C standard and the relevant post-C99 technical reports???.
The Perl standard documents existing practice where possible. That is, most features must be tested in an implementation before being included in the standard. The CERT Perl secure coding standard has a different purpose. When existing practice serves this purpose, that is fine, but the goal is to create a new set of best practices, and that includes introducing some concepts that are not yet widely known. To put it a different way, the CERT Perl secure coding guidelines are attempting to drive change rather than just document it.
