try $this->foobar(); catch ($e) {
    // Much amount of error handling
}

// or maybe

try $this->foobar(); catch ($e) $this->handleException($e);

OK, the first example is better, but both reads like quite nice :)

try someVeryDifficultStuff(); catch ($e) { /* handle */ }


Regards,
Sebastian
