note jthalhammer [dist://Perl-Critic] does exactly that. It's an extensible static source code analyzer based on PPI. It enforces about 60 of Damian's Best Practices, plus a few others. The current interfaces are the <code> perlcritic </code> command-line and [dist://Test-Perl-Critic] which runs via test a script. But I could easily see hooking into a source filter that analyzed the code at compile-time. <P/> -Jeff 486213 486500
