你已经看过了吗 Moose::Cookbook::Basics::DateTime_ExtendingNonMooseParent 和 MooseX::NonMoose ?

MooseX::Declare 和 MooseX::NonMoose

package My::App;

use Moose;
use MooseX::NonMoose;
extends 'CGI::Application';

sub setup {
    my $self = shift;
    $self->start_mode( 'main' );

    $self->run_modes(
        map { $_ = $_->name;
              /^rm_ (?<rm>.+) $/x ? ( $+{rm} => $_ ) : ()
        } $self->meta->get_all_methods
    );
}

"My::App"

package My::Login;
use Moose;
extends 'My::App';

sub rm_main { 'it works!' }

"My::Login"

#!/usr/bin/perl

use strict;
use warnings;

# For testing on the command line
use FindBin qw( $Bin );
use lib $Bin;

use My::Login;

my $app = My::Login->new;

$app->run;

C:\Temp\f> t
Content-Type: text/html; charset=ISO-8859-1

it works!
