Okay... I'm a little confused. Andi, would you take a look at PEAR::isError() in php4/pear/PEAR.php(.in), and can you say whether or not it should take a reference? IE, is the inconvenience of not being able to directly pass it a function result that might be a boolean justified by the performance gain, if there _is_ a performance gain? -chuck -- Charles Hagenbuch, <chuck@horde.org> "If you can't stand the heat, get out of the chicken!" - Baby Blues
