Thanks for the feedback, unfortunately fixing the extended class name does not solve the problem :(

Well, not surprising, fixing thinkos rarely fixes "bugs" :)

Well, it might be considered a bug that Moo isn't as helpful as Moose, Moose actually checks the class is blessed into the right, Moo doesn't

Quick workaround is 

sub MenuBar::Item::BUILD {
    my $self = shift;
    bless $self, __PACKAGE__ ;
    $self->Append( $self->item_quit );
    return $self;
}

Now why doesn't Wx::Menu obey the common rules of subclassing/inheritance, well not all things in wxPerl are mean to be subclasses, and indeed menu/menubar are indeed odd candidates for that ... some of this is explained in Re: wxperl-users scalar reference objects?

As you can see a Wx::Menu isn't a hashref, its a scalar ref 

#!/usr/bin/perl --
use Wx qw[ :allclasses ]; 
{ package MMenu;  use base qw/ Wx::Menu /; 1; }
{ package MFrame; use base qw/ Wx::Frame /; 1; }
package main;
print join "\n", 
    MMenu->new,
    MFrame->new,
;;;;;
__END__
Wx::Menu=SCALAR(0x3f9afc)
MFrame=HASH(0x99b30c)

FWIW, not everything needs to be subclasses, ex wxperl_usage
