Description

The following code:

class A
{
    public static function b()
    {
        echo static::class;
    }
}

class B extends A
{
}

$c = ['B', 'b'];

$d = \Closure::fromCallable($c);

$r = new \ReflectionFunction($d);

var_dump($r->getClosureScopeClass());

$d();

Resulted in this output:

object(ReflectionClass)#41 (1) {
  ["name"]=>
  string(1) "A"
}
B

But I expected this output instead:

object(ReflectionClass)#41 (1) {
  ["name"]=>
  string(1) "B"
}
B

Right now, there is no way to turn back a named closure into a regular callable because reflection doesn't give back the "called class" ("B" here.)
