Indeed, I have looked at the sources and found out that now the implementations of 'Set' and 'Map' are basically the same.
The major achievement of (the new) Data.Set and Data.Map are canonical names that should be used in conjunction with qualified imports: import qualified Data.Set as Set import qualified Data.Map as Map import Data.List as List
Presumably the new implementation of size-balanced trees is (much?) more efficient than the old one from 'FiniteMap'.
There is no difference in efficiency, Data.Map is not slower than the old FiniteMap. Cheers Christian
