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 ==7.8.2

order to get people to be explicit about which
version of base they use.
