  Log:
  After GHC 7.2 a new `casMutVar#` primop became available, but was not yet
  exposed in Data.IORef. This package fills that gap until such a time as
  Data.IORef obsoletes it. Further, in addition to exposing native Haskell
  CAS operations, this package contains "mockups" that imititate the same
  functionality using either atomicModifyIORef and unsafe pointer equality
  (in Data.CAS.Fake) or using foreign functions (Data.CAS.Foreign).
  These alternatives are useful for debugging. Note that the foreign option
  does not operate on IORefs and so is directly interchangeable with `Data.CAS`
  and `Data.CAS.Fake` only if the interface in `Data.CAS.Class` is used.
