Dear internals,

Don't you think allowing to throw an exception as the right side of null coalescing operator would be a good idea?

Something like:

echo $a ?? throw new \RuntimeException('foo');

Regards,
Tim

Sometimes that would be really helpful. What you can do is something like
that:

function raise(Throwable $t) {
    throw $t;
}

$a = $a ?? raise(new \RuntimeException("foo"));
