It could be especially useful when used inside classes. Probably the same as bug #6566, but if it disappeared after php3, it certainly should be turned on again in php5 Expected result: ---------------- Compute default arguments when calling a function, that can create those itself. It will help if you need something like: function A ($arg = NULL) { if($arg == NULL) $arg=$another_arg; ..... } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29863&edit=1
