  * export Data.Map.toDescList, foldlWithKey, and foldrWithKey (trac ticket 2580)
  
  toDescList was previously implemented, but not exported.
  
  foldlWithKey was previously implemented, but not exported.  It can be used to
  implement toDescList.
  
  foldrWithKey is already exported as foldWithKey, but foldrWithKey is explicitly
  the mirror of foldlWithKey, and foldWithKey kept for compatibility.
