What im trying to allow for is sorting by iterator as well as standard
arrays, for example :
// assume en_US as default locale
$coll = new Collator("en_US");
$iter = new TextIterator("The rain in Spain drop gently on the Plains",
TextIterator::WORD);
var_dump( $coll->sort($iter)); // returns the sorted list of words
$expr = new Regex($patttern, $input, $flags);
var_dump($coll->sort($expr, SORT_DESC)); // Sorts matches in descending
order

i wrote this more than ayear ago and i remember copying it from engine code.

which dtor handler ?

That helps. Thanks a lot....
