I have this code, which works, that allows me to access some custom methods in a role I created. For example:

{ package Server;

  use Carp;
  use Moose;
  use Net::OpenSSH;
  use Config::Simple;
  with 'MyOpenSSH';

  has 'ssh' => (is => 'ro', isa => 'Net::OpenSSH', required => 1, hand
+les => qr/.*/, );
}

{ package MyOpenSSH;
  use Moose::Role;

  sub grab {
    my $self = shift;
    $self->_check_command(@_);
    my $result = $self->ssh->capture(@_);
    return $result if ($? == 0 && !$self->ssh->error);
  }
}

use Server;
my $server = Server->new(ssh => Net::OpenSSH->new('me@10.0.1.22'));
print $server->grab('ls');

I'm trying to get the above to work following the documentation for Moose delegation which states the following:

You can use a role name as the value of handles:

  has 'uri' => (
      is      => 'ro',
      isa     => 'URI',
      handles => 'HasURI',
  );

Moose will introspect the role to determine what methods it provides a
+nd create a name-for-name mapping for each of those methods.

So I tried modifying the attribute line in the Server code like so:

  has 'ssh' => (is => 'ro', isa => 'Net::OpenSSH', required => 1, hand
+les => 'MyOpenSSH', );

However, this just results in an error:

You cannot overwrite a locally defined method (grab) with a delegation

Other attempts to get this working resulted in failure as well. What am I missing?
