Re: RFC: Class::CGI

I was wondering if there was any benefit in this kind of interface

  use Class::CGI
    handlers => {
      customer => 'Class::CGI::Customer',
      email    => 'Email::Loader'
    };

  my $cgi = Class::CGI->new;
  my $customer = $cgi->customer();      # dispatch to C::C::C
  my $email    = $cgi->email();         # dispatch to E::L
  my @sports   = $cgi->param('sports'); # as per usual
  # validate email
  $customer->email($email);
  $customer->save;

Surmising, if you've declared the handlers, perhaps you can construct things so that these handlers become methods in this instance of Class::CGI. You just have to come up with a way to make sure the methods are only in this scope of the "use Class::CGI" declaration. I

That changes the design dramatically since I would then have to delegate to the real CGI::Simple object lest someone have paremeters named "keywords", "param" or "upload" and innapropriately overloading things. Still, it might be a cleaner interface. I would simply have to find an easier way for folks to get at the underlying CGI object, if necessary. I would hate arbitrarily outlawing certain parameters because they're "reserved" methods. Some folks wouldn't be able to use the code that way since it would be tough to integrate with an existing site which used the reserved parameter names.

I could do something like this:

use CGI;
use Class::CGI
  handlers => {
    customer => 'Class::CGI::Customer'
  };
my $cgi = Class::CGI->new( cgi => CGI->new );

That would also have the advantage of allowing folks to use any class which implements the required CGI methods (just param(), at this time). It has the disadvantage of forcing them to explicitly load in the other module and I was hoping to do away with that. I could be done implicitly, but that brings back the problems mentioned in the first paragraph. I'll have to think about this.
