Data.Ix.Enum

Description

Implementations of `Ix` methods in terms of `Enum` methods.

For a type `T` of class `Enum` you can easily define an `Ix` instance by copying the following code into your module:

    import qualified Data.Ix.Enum as IxEnum

    instance Ix T where
       range           = IxEnum.range
       index           = IxEnum.index
       inRange         = IxEnum.inRange
       rangeSize       = IxEnum.rangeSize
       unsafeIndex     = IxEnum.unsafeIndex
       unsafeRangeSize = IxEnum.unsafeRangeSize
