WeakMap iteration

--EXPECT--
Empty loop:
Simple loop:
object(stdClass)#2 (0) {
}
int(0)
object(stdClass)#3 (0) {
}
int(1)
object(stdClass)#4 (0) {
}
int(2)
Object removed during loop:
object(stdClass)#2 (0) {
}
int(0)
object(stdClass)#3 (0) {
}
int(1)
object(stdClass)#4 (0) {
}
int(2)
By reference iteration:
object(WeakMap)#1 (2) {
[0]=>
array(2) {
["key"]=>
object(stdClass)#2 (0) {
}
["value"]=>
&int(1)
}
[1]=>
array(2) {
["key"]=>
object(stdClass)#4 (0) {
}
["value"]=>
&int(3)
}
