[PEPr] Comment on RFC::EvalForbiddance

Clay Loveless (http://pear.php.net/user/clay) has commented on the proposal for RFC::EvalForbiddance. Comment: This seems like a good idea in general, but there are cases where eval is the only way to go -- such as this snippet to simultaneously avoid is_a() deprecation notices in PHP5, and parse errors in PHP4: $is_a = false; $major_php_version = PHP_VERSION; if (intval($major_php_version{0}) < 5) { if (is_a($obj, 'some_class')) { $is_a = true; } } else { $is_a = eval("return ($obj instanceof Some_Class) ? true : false;"); } It seems like this type of usage should be allowable -- no external data is being handed off to eval() in this example, making it pretty safe usage.
