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).
