As I told you in previous reply, I'm working on block-expressions as well.
So if PHP has block-expressions you can do the same this way:
$y = switch ($x) {
case 1 => eval {
$arr = get_array();
give array_pop($arr);
},
case -1 => eval {
$arr = get_array();
give array_shift($arr);
},
default => null,
};
Which is obviously cleaner and more powerful.
Are you saying it is literally impossible given the current engine, or just

Yes, it is impossible to break out of an ongoing function call without
exceptions.

No, I was not angry. Just a little bit tired. I appologize making you feel
that way.
