  my $class  = $proto->create; # via Data::Object::Prototype
  my $object = $class->new(name => '...');

registry

The registry function returns the registry singleton object where mapping between namespaces and type libraries are registered.

registry example

  registry; # Data::Object::Registry

reify

  reify(Str $arg1) : Object
