A few questions:
- Does Class::CGI::new consume query data and/or request body directly? Does it use an internal instance of a CGI object, and if so can it use an existing one? (In which case I would expect it to copy over all the param data triggering any relevant handlers as it encounters them. Of course, that might lead to ordering problems if something later in the form is sensitive to something earlier in the form.)
- My first thought when reading this was that you were referring to class-ifying structured data within forms, but from the longer examples I see that you're mostly just abstracting away the untaint and ->new() steps. So, aside from the sugaring, I'm not sure what benefits this provides. Is there a way to express interrelations between elements? If my instantiation of My::Customer needs the contents of other fields as well, do I have to go back to vanilla CGI?
- How hard would it be to have handlers that took on multiple input parameters? For example, to have a single handler that gathers address1, address2, city, state and zip_code and returns a single My::StreetAddress? (This is similar to, but not the same as the previous.)
Still, interesting concept. ++
