--FILE--
<?php
function test(...$args) {
var_dump($args);
}
class Foo implements IteratorAggregate {
public function getIterator(): Traversable {
throw new Exception('getIterator');
}
}
function gen() {
yield 1;
yield 2;
throw new Exception('gen');
}
try {
test(1, 2, ...new Foo, ...[3, 4]);
} catch (Exception $e) { var_dump($e->getMessage()); }
try {
test(1, 2, ...gen(), ...[3, 4]);
} catch (Exception $e) { var_dump($e->getMessage()); }
