I had a similar problem. I receive a minimal abstract object and changed it into a specialized one to make life easier. What I did was creating a new class "Labrador" with the superclass "Dog" and a role "LabradorMethodsAndAtributes". Well, in my case it wasn't dogs.
Shortened, adjusted, unrunable code:
my $class_name = "Felidae::Tiger";
# Does the class already exist?
# No, create it
my $superclass = "Felidae";
my $role_name = "Felidae::Role::Tiger";
# create the Role
my $role = Moose::Meta::Role->create($role_name);
# A leopard does not have stripes but spots
( is => 'rw',
isa => 'Int',
... # builder, lazy etc
my $my_class = Moose::Meta::Class->create(
superclasses => [$superclass],
roles => [$role_name],
my $garfield = $class_name->new($felidae_obj);
Now you have an object which isa "Felidae" and a "Tiger" and does "stripecount".
And it came to pass that in time the Great God Om spake unto Brutha, the Chosen One: "Psst!"
