This looks fine to me. "best" is hard to meet. I'ld suggest: foldr (uncurry Map.insert) Efficiency should be tested, though. Cheers Christian P.S. Data.Map contains the following definition: fromList xs = foldlStrict ins empty xs where ins t (k,x) = insert k x t _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
