Description:
------------
See code.

On alpha 1 this returns "EngineException caught".

On alpha 2 it returns:

Fatal error: Uncaught TypeError: Argument 1 passed to takesInt() must be of the type integer, string given

I suspect it's something to do with the new Throwable support, at a guess.

This is the first bug I've raised, so lemme know if I've done it wrong,or you need more info. Cheers.

Test script:
---------------
try {
    function takesInt(int $x){
        return true;
    }

    takesInt('not an int');
} catch(EngineException $e) {
	echo 'EngineException caught<br>';
}
