1. fromList :: HasCallStack => [a] -> NonEmpty a

   base	Data.List.NonEmpty

   Converts a normal list to a NonEmpty stream. Raises an error if given an empty list.

2. fromList :: IsList l => [Item l] -> l

   base	GHC.Exts

   The fromList function constructs the structure l from the given list of Item l

3. fromList :: IsList l => [Item l] -> l

   base	GHC.IsList

   The fromList function constructs the structure l from the given list of Item l

4. fromList :: [(Key, a)] -> IntMap a

   containers	Data.IntMap.Internal

   Create a map from a list of key/value pairs.

   fromList [] == empty
   fromList [(5,"a"), (3,"b"), (5, "c")] == fromList [(5,"c"), (3,"b")]
   fromList [(5,"c"), (3,"b"), (5, "a")] == fromList [(5,"a"), (3,"b")]
   

5. fromList :: [(Key, a)] -> IntMap a

   containers	Data.IntMap.Lazy

   Create a map from a list of key/value pairs.

   fromList [] == empty
   fromList [(5,"a"), (3,"b"), (5, "c")] == fromList [(5,"c"), (3,"b")]
   fromList [(5,"c"), (3,"b"), (5, "a")] == fromList [(5,"a"), (3,"b")]
   

6. fromList :: [(Key, a)] -> IntMap a

   containers	Data.IntMap.Strict

   Create a map from a list of key/value pairs.

   fromList [] == empty
   fromList [(5,"a"), (3,"b"), (5, "c")] == fromList [(5,"c"), (3,"b")]
   fromList [(5,"c"), (3,"b"), (5, "a")] == fromList [(5,"a"), (3,"b")]
   

7. fromList :: [(Key, a)] -> IntMap a

   containers	Data.IntMap.Strict.Internal

   Create a map from a list of key/value pairs.

   fromList [] == empty
   fromList [(5,"a"), (3,"b"), (5, "c")] == fromList [(5,"c"), (3,"b")]
   fromList [(5,"c"), (3,"b"), (5, "a")] == fromList [(5,"a"), (3,"b")]
   

8. fromList :: [Key] -> IntSet

   containers	Data.IntSet

   Create a set from a list of integers.

9. fromList :: [Key] -> IntSet

   containers	Data.IntSet.Internal

   Create a set from a list of integers.

10. fromList :: Ord k => [(k, a)] -> Map k a

    containers	Data.Map.Internal

    Build a map from a list of key/value pairs. See also fromAscList. If the list contains more than one value for the same key, the last value for the key is retained. If the keys of the list are ordered, a linear-time implementation is used.

    fromList [] == empty
    fromList [(5,"a"), (3,"b"), (5, "c")] == fromList [(5,"c"), (3,"b")]
    fromList [(5,"c"), (3,"b"), (5, "a")] == fromList [(5,"a"), (3,"b")]
