That's very true. And I feel free to break any of my own rules if the situation warrants it. I state this one strongly because I try to avoid breaking it if at all possible. I find that reshuffling the data to support one-parameter logic helps me build better, more robust code.

I'll be happy to scale this one back to "try to code for single parameters if possible" if the rest of the monastery will give up equivalent dicta, like "use CGI.pm or die." ;-)
