Hi Matt & Ondřej,
I wanted to give my +1 to this proposal.
I was curious to see how fibers might interact with this declaration, since it is possible to create
a fiber that can not return. So, I compiled your branch and gave it a try.
```
$fiber = new Fiber(function (): noreturn {
while (true) {
Fiber::suspend(\random_int(0, 100));
}
});
$result = $fiber->start();
for ($i = 0; $result; ++$i) {
echo $result, "\n";
$result = $fiber->resume();
}
echo "Generated ", $i, " numbers before generating zero.\n";
```
This short script works just as expected, cool! :-D
Cheers,
Aaron Piotrowski
