Description:
------------
I would like to overload array access like this

<?php
class MyClass {
  private $parameters = array();

  function __set( $name, $value, $key ) {
    if( ! isset( $this->parameters[ $name ] ) ) {
      $this->parameters[ $name ] = array();
    }
    $this->parameters[ $name ][ $key ] = $value;
  }
}

$object = new MyClass;
$object->a[ 'x' ] = 'value';
?>
