First off, your list() method should return an iterator, which you would use as while (my $object = $iterator->next) { ... }. Each item in a list shouldn't know who the next item is - that's for the iterator to know.

But, if you insist on doing this, you want to do the following: 

sub load_next{
    my ($self, %arguments) = @_;
  my @next = @{$self->storage_next_list};
  my $new_self = shift @next or return;
  $_[0] = $new_self;
  $self->storage_next_list(list=>\@next);
  return $new_self;
}

This is very poor coding and should be avoided.

I shouldn't have to say this, but any code, unless otherwise stated, is untested
