trait T {
public function equal(C $type): bool {
return $type instanceof self && $this->value === $type->value;
}
}
class C1 extends C {
use T;
public function __construct(private int $value) {}
}
class C2 extends C {
use T;
}
$x = new C1(1);
var_dump($x->equal($x));
var_dump($x->equal($x));
$a = new C2("aaa");
var_dump($a->equal($a));
var_dump($a->equal($a));Resulted in this output:
