Hi Monks, Suppose i have the following class: 
package GSM::Cell;
use Moose;
use MooseX::AttributeHelpers;

with qw(GSM::Cell::Role::BcchChecks);

has 'BCCH' => (is => 'rw', required => 1);
has 'LAC' => (is => 'ro', required => 1);
has 'CI' => (is => 'ro', required => 1);

has 'ADJACENCIES' => ( 
                metaclass => 'Collection::Hash',
                             is => 'rw', 
                            isa => 'HashRef', 
                    default => sub {+{}},
                provides  => {
           exists => 'exists_adjacency',
           keys   => 'adjacency_IDs',
           get    => 'get_adjacency',
           set    => 'add_adjacency',
        },
        );

and a little later i have the following role : 
package GSM::Cell::Role::BcchChecks;
use Moose::Role;

#requires qw(get_adjacency); # - error

sub list_bcchs {
    my $self = shift;
    my %list = map {$_->BCCH => 1} $self , map($self->get_adjacency($_
+)->CELL , $self->adjacency_IDs);
    my @list = sort keys %list;
    @list;
}

1;

If i uncomment the requires qw(get_adjacency) in GSM::Cell::Role::BcchChecks i get the error GSM::Cell::Role::BcchChecks requires the method 'get_adjacency' to be implemented by 'GSM::Cell' even though the method "get_adjacency" is a valid method that is auto-provided when using MooseX::AttributeHelpers. How can i nevertheless enable such a check? I would ideally like to avoid a  croak "Not a GSM::Cell" unless $self->isa('GSM::Cell') type of solution.
