Pixie::Info - A magical way of having out of band info

  use Pixie::Info;

  $obj->Pixie::Info::set_info($a_value);
  ...
  $info = Pixie::Info::get_info($obj) # could use OO style here too...

Associates an id (could be an object itself) to any other object or ref. if you destroy the ref and you dont hold any copy of $id, $id gets also destroyed.

Be carefully about circular references (Scalar::Util::weaken is your friend.
