Would it be possible to put everything concerned with unique
identifiers in GHC into a separate package on Hackage?
I have wrapped up (a tiny subset of) GHC's uniques into the package
`uniqueid` and put it on Hackage:
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/uniqueid
It only provides
type Id
hashedId :: Id -> Int
type IdSupply
initIdSupply :: Char -> IO IdSupply
splitIdSupply :: IdSupply -> (IdSupply,IdSupply)
idFromSupply :: IdSupply -> Id
instance Eq Id
instance Ord Id
instance Show Id
The main difference is due to my fear of depending on the foreign
function `genSymZh` which I replaced by a global counting IORef.
The other difference is that the Show instance does not rely on GHC's
static flags and can hence be used outside of GHC sessions.
The code is on github:

Extensions welcome!
Cheers,
Sebastian
