I found the package 'enumsets' in ArchLinux:  http://aur.archlinux.org/packages.php?ID=18116

This points to Hackage, but there is no such package.

It sounds like something I could need: A simple Haskell 98 wrapper around Word32, Word16, Word8, that are interpreted as bitfields, providing set operations with elements of an Enum type. I frequently like to have this when interfacing to C. I know of Edison.EnumSet, but my emphasis is on simplicity (i.e. Haskell 98).

Maybe it's referring to (or you could use) one of the following:

* http://hackage.haskell.org/package/EnumContainers * http://hackage.haskell.org/package/EnumMap

No they are different, they rely on containers' IntMap.
