The proposed modification of function_exists() will break existing code: <?php namespace foo; if (!function_exists(__NAMESPACE__.'\\bar')) { function bar() { // .... } } ?> as soon as a bar() function is defined in global scope, with no obvious hint why it suddenly broke. You should either (from my increasing order of preference): * acknowledge it in the “Backward Incompatible Changes” section; * default the $autoload extra parameter to false; * keep the current semantics, that using a namespaced or qualified function name, (including a function name given as string, which is implicitly fully qualified), doesn’t fall back to the global scope, — even when a previous use of the same function name did trigger the fall back, see: https://3v4l.org/mnVWO (Independently of any mechanism introduced to avoid to repeatedly trigger the function autoloader.) 2. If you add function autoloading, you ought to support constant autoloading as well, of course. —Claude
