I think v1.88 is the latest docs version. Handle() and Object() functions are a bit underdocumented. I tried them out a couple of years ago, but had some problems and gave up on them. You can live without them, really.
In the above code Handle() is just used because it returns an integer for an object. It doesn't matter what the integer is, as long as they're different for all objects of the type.
