Category:       Prelude
Synopsis:
    A redefinition of the Prelude's Enum class in order to render it safe.
Description:
    A redefinition of the Prelude's Enum class in order to render
    it safe. That is, the Haskell Language Report defines pred,
    succ, fromEnum, and toEnum to be partial functions when the
    type is Bounded, but this is unacceptable. We define a new
    type-class hierarchy for enumeration which is safe and also
    generalizes to cover types which can only be enumerated in one
    direction.

Tested-With:
    GHC ==6.12.1, GHC ==7.6.1, GHC ==7.8.0

Flag base4
    Default:     True
    Description: base-4.0 emits "Prelude deprecated" messages in
                 order to get people to be explicit about which
                 version of base they use.
