I'm using the "AUTOLOAD" already. The "AUTOLOAD" is fine for non 
existing runmodes.
But I think this is not enough for what I'm writing about: no entries at 
all matching the in dispatch table of CGI::Application::Dispatch.
CGI::Application::Dispatch will not match any entry in the table for a 
given request, so it will not instantiate any subclass of 
CGI::Application (in which the "AUTOLOAD" might be defined).
The "AUTOLOAD" is ok to handle requests like:
   /myapp/welcome/start
where there is no 'start' runmode in a Class named "Welcome" (which is a 
CGI::Application subclass), but I'm taking about requests like:
   /myapp/foo/start
where the Class "Foo" does not exist at all.
