Hi Monks, Trying to use override with my Moose::Role doesn't work if I am overriding a parent role's implementation.

package top;
use Moose::Role;
requires    'token';
sub foo {
    print "foo\n";
}

sub useful_method{
   print "I'm useful\n"
}

package bottom;
use Moose::Role;
with 'top';

override 'foo' => sub {
    print "bar\n";
};

package something;
use Moose;
with "bottom";

sub token {
    print "implement me in the concrete class";
}

package main;
my $something = new something;
$something->foo;

[download]

Gives "Cannot add an override of method 'foo' because there is a local version of 'foo'". Just putting a normal sub instead of override doesn't work etither. I get: "Due to a method name conflict in roles 'bottom' and 'top', the method 'foo' must be implemented or excluded by 'something'". Basically the problem is: I want to use top's useful_method and bottom's foo and I don't want to implement "token" until the concrete class. Why can't I use Roles in this way?

Thanks!
