is_a() behaves like

  return get_class($object) == strtolower($class);

but should behave like

  return get_class($object) == strtolower($class) ||
                   is_subclass_of($object, $class);

I can give a copy of the commercial application where this happens to the php-developer who wants to fix this bug.
