perfect:
package FN::Utils;
use MooseX::Role::Parameterized;
use MooseX::Types::Moose qw(Str);
parameter table => (isa => Str, required => 1);
role {
my $p = shift;
my $table = $p->table;
method some_db_op => sub { ... do something with $table ... };
}
package FN::User;
use Moose;
with 'FN::Utils' => { table => 'fnuser' };
Only downside: you can't compose parameterized roles with other roles. This is
a known bug, and we're planning on fixing it at YAPC if we haven't done it by
then.
hdp.
