Modified files: libraries/base package.conf.in libraries/base/Data FiniteMap.hs Set.hs Added files: libraries/base/Data IntMap.hs IntSet.hs Map.hs Log: Add Data.Map, Data.Set, Data.IntMap and Data.IntSet from Daan Leijen's DData library, with some modifications by JP Bernardy and others on the libraries@haskell.org list. Minor changes by me to remove the last references to DData, and add a DEPRECATED copy of the old Data.Set interface to the new Data.Set.
Data.FiniteMap is now DEPRECATED.

I must admit that I didn't follow the data structure discussion in every detail, but I find something confusing: In Data.FiniteMap.addListToFM_C, the combining function gets the old value as the 1st argument and the new value as the 2nd one. In Data.Map.insertWithKey (and friends), this seems to be the other way round, which is undocumented and *very* confusing when trying to port things from FiniteMap to Map. Is there a deep reason for this? Cheers, S.
