1. fromListWithKey :: (Key -> a -> a -> a) -> [(Key, a)] -> Word64Map a

   ghc	GHC.Data.Word64Map.Lazy

   Build a map from a list of key/value pairs with a combining function. See also fromAscListWithKey'.

   let f key new_value old_value = show key ++ ":" ++ new_value ++ "|" ++ old_value
   fromListWithKey f [(5,"a"), (5,"b"), (3,"b"), (3,"a"), (5,"c")] == fromList [(3, "3:a|b"), (5, "5:c|5:b|a")]

2. fromListWith :: (a -> a -> a) -> [(Key, a)] -> Word64Map a

   ghc	GHC.Data.Word64Map.Strict

10. fromListAccum :: [(Key, Value)] -> Object

    attoparsec-aeson	Data.Aeson.Parser.Internal

    fromListAccum kvs is an object mapping keys to arrays containing all associated values from the original list kvs.

    >>> fromListAccum [("apple", Bool True), ("apple", Bool False), ("orange", Bool False)]
