If you notice the implementation of ``M\ object dispose``:
```
M: object dispose [ t >>disposed dispose* ] unless-disposed ;
```
That hints at a ``disposed`` slot. Well, really that should be a method on
``disposable`` but there is one place where we take advantage of the
"requirement" for a slot that tracks if it was disposed previously or not
and calls ``dispose*``.
So basically, if you're a ``disposable`` and you have a slot that tracks
"was I previously disposed or not" then you can implement ``dispose*``
otherwise, you should provide a proper implementation of ``dispose``.
