I think I've got attribute handlers down for perl Natives! 
package tree;
      has '_branches' => (
               traits    =>  ['Hash'], 
               is        => 'rw', 
               isa       => 'HashRef[Any]', 
               handles   => {
                  _set_branch  => 'set',
                  _is_branch   => 'defined',
                  _list_branches => 'keys',
                  _branch => 'get'
               },
               trigger   => sub {
                  my($self,$hash) = @_;
                  $self->_build_branch($hash);
               }

      );


sub _build_branch{
  my($self,$hash);
  # do stuff!
  #return altered or coerced hash
  return $hash;
}

What do you think? But let's say for example I have a LinkedList object with the following methods 
LinkedList{}
LinkedList.append()
LinkedList.insert()
LinkedList.size()
LinkedList.has_children()
LinkedList.remove()
LinkedList.split()

Is there a way handle the object's methods via Moose Attributes (without using MooseX) - similar to this? 
package Bucket;
      has '_linkedlist' => (
               traits    =>  ['LinkedList'], 
               is        => 'rw', 
               isa       => 'LinkedListRef[Any]', 
               handles   => {
                  _add_link  => 'append',
                  _insert_link   => 'insert',
                  _count_links => 'size',
                  _del_link => 'remove',
                  _split_at_link => 'split',
                  _has_sublinks => 'has_children', 
               }
       };

It would be great if there was a way to do this, but I'm concerned maybe I've misunderstood something somewhere about how or why to create handlers for non-native attributes. Your wisdom is appreciated!
