New Comment:
I have discussed with ekneuss about this FR for a bit.
thanks to ekneuss, we found there are some limits,
1. since PHP is a dynamic language, then for $obj->function, we can not
determine what $obj is, so if we want to implement this FR, we have to do the
check at run-time.
2. there is another question while for following codes:
function bar($i) {
if ($i == 42) {
$obj->someFuncThrowException();
}
}
so, should we trigger WARNING all the times?
3. unlesss ZEND_CATCH is executed, we have no idea what type of exception will
be caught by catch, so, if we implement a whole exception type check, we will
need: exception autoload, and catch statements analyse , which will bring a
obvious performance slow down..
anyway, I can do more research later , thanks :)
