// % note 1: others here in order to be able to simulate more types (though should not trigger
// % note 1: aggregates like E_STRICT or E_ALL).
// % note 1: See also our experimental at() function (to mimic the @ error suppressor)
// - depends on: echo
// * example 1: trigger_error('This will just be a notice');
// * returns 1: true
// Fix: get to work with set_error_handler()'s handler when that is added
