EnumMap is a generalization of IntMap that constrains the key to Enum rather than forcing it to be Int. I have no idea what impact this has on performance,
Will it have an impact on correctness? There are some funky Enum instances around: Prelude> map fromEnum [1,1.5,2] [1,1,2] Prelude Data.Int> fromEnum (10000000000 :: Int64) *** Exception: Enum.fromEnum{Int64}: value (10000000000) is outside of Int's bounds (-2147483648,2147483647) -k -- If I haven't seen further, it is by standing in the footprints of giants
