1. Clearly, I’m making an argument for being able to write scripts that run whether or not you have mod_perl installed, so that readers who can’t install mod_perl or who elect not to will be able to run most of the scripts in this book without modification.There is a counterargument, which is that if you know you’re going to use mod_perl, you can get even better performance by dispensing with Apache::Registry and interacting more directly with Apache.
