I've been reading a lot of posts lately on the CGI::App mailing list about using CGI::Application::ValidateRM (RM == Run Mode); I finally went and checked it out.

CGI::App::ValRM uses Data::FormValidator in order to do its magic. Interestingly, D::FV is built much like how I've buit our formHandlers library at work — you specify a list of required fields, and a list of fields that need to be validated against criteria, then provide the criteria. It goes exactly how I would have done our libraries had we been working in perl — supplying the constraint as a regexp or anonymous sub in a hashref for the field.

Anyways, it looks like the combination of CGI::App::ValRM with CGI::App could greatly simplify any form validations I need to do on the site, which will in turn make me very happy!
