Newtype of Int, to be clear.

1) There is a #ifdef define(__GLASGOW_HASKELL__), which conf
type Unique!
(In my view) it’s usually much better not to use type classes unless you

Dear Simon, et al,
Looking at Unique, there are a few more design choices that may be outdated,
and since I'm polishing things now, anyway, I figured I could update it on more
fronts.
