| Subject: | Attribute delegated in one role does not satisfy requires of another role |

I have one role that provides a method by delegating it to an attribute, and another
role that requires that method. When I try composing those two roles, Moose does
not see the delegated method as satisfying the requires clause.
I'm running Perl 5.14.2 under perlbrew on Fedora 16, with up-to-date CPAN,
including Moose 2.0602.
Here's a simplified example case, which gives the error:
'DelegatedYum|NeedsYum' requires the method 'yum' to be implemented by 'Composed'
package HasYum;
use Moose;
has yum => ( is => 'ro', default => 37 );
package DelegatedYum;
use Moose::Role;
has has_yum => (
is => 'ro',
default => sub { HasYum->new() },
handles => ['yum']
);
package NeedsYum;
use Moose::Role;
requires 'yum';
package Composed;
use Moose;
#with qw{ NeedsYum DelegatedYum };
with qw{ DelegatedYum NeedsYum };
