Yes. The real power of CGI::App shows through when you write a re-usable
module, so that can be used from two or more instance scripts at the
same time. You might do this when you want to present the same
application, but with a different template look or configuration
variables in place.

All correct.

First, you have the option of handling the case. With an AUTOLOAD
routine. If that doesn't return output or is missing, your webserver
likely display the "500", Internal Server Error message. I use a generic
AUTOLOAD in all my CGI::App modules to simply return a message that the
desired 'page' could not be found. It looks something like this:
AUTOLOAD => sub {
my $self = shift;
return $self->error(title=>'Page not found', msg=> "(runmode tried was:
".$self->query->param('rm').")")
}
This is referencing an "error" run mode, that just fills in a basic template and
returns it.
