Hi... cf

Haskell Report appendix A:

  class Enum ...
  -- Minimal complete definition:
  --   toEnum, fromEnum

Glasgow Haskell v4.02:

KDBPrim.lhs:40:
    Warning: No explicit method nor default method for `enumFromThen'
             in an instance declaration for `Enum'

Hmm... this seems to be a bug in the Haskell report too... the 
definition is missing from the example Prelude.  Cc'd to Haskell list.
