I don't know whether I proposed it already ...
I wrote a package called enumset. It provides low-level bitsets like they
are used by wxWidget. The definition is essentially:
newtype EnumSet storage index = EnumSet storage
E.g. with
data Style = Bold | Italic | Underlined deriving (Enum)
the type (EnumSet Word32 Style) represents a subset of {Bold, Italic,
Underlined} stored as a bitfield in a Word32.
http://hackage.haskell.org/packages/archive/enumset/0.0.4/doc/html/Data-EnumSet.html
The other modules can be used to manage bitfields where not individual
bits must be processed, but there are groups of bits, where each group
represents a value.
