callable reflection should work

[muglug]

function reflectCallable(callable $callable): ReflectionFunctionAbstract {
  if (\is_array($callable)) {
    return new \ReflectionMethod($callable[0], $callable[1]);
  } elseif ($callable instanceof \Closure || \is_string($callable)) {
    return new \ReflectionFunction($callable);
  } elseif (\is_object($callable)) {
    return new \ReflectionMethod($callable, '__invoke');
  } else {
    throw new \InvalidArgumentException('Unrecognized type of callable');
  }
}

Expected: no issue
Actual: some issues
