1. data Map s k a

   refined-containers	Data.Map.Refined

   A wrapper around a regular Map with a type parameter s identifying the set of keys present in the map. A key of type k may not be present in the map, but a Key s k is guaranteed to be present (if the s parameters match). Thus the map is isomorphic to a (total) function Key s k -> a, which motivates many of the instances below. A Map always knows its set of keys, so given Map s k a we can always derive KnownSet s k by pattern matching on the Dict returned by keysSet.

2. data Map s k a

   refined-containers	Data.Map.Strict.Refined

   A wrapper around a regular Map with a type parameter s identifying the set of keys present in the map. A key of type k may not be present in the map, but a Key s k is guaranteed to be present (if the s parameters match). Thus the map is isomorphic to a (total) function Key s k -> a, which motivates many of the instances below. A Map always knows its set of keys, so given Map s k a we can always derive KnownSet s k by pattern matching on the Dict returned by keysSet.

3. data Map k a

   verset	Verset

   A Map from keys k to values a. The Semigroup operation for Map is union, which prefers values from the left operand. If m1 maps a key k to a value a1, and m2 maps the same key to a different value a2, then their union m1 <> m2 maps k to a1.

4. map :: (a -> b) -> [a] -> [b]

   base	Prelude

   map f xs is the list obtained by applying f to each element of xs, i.e.,

   map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
   map f [x1, x2, ...] == [f x1, f x2, ...]
   

   this means that map id == id

   Examples

   >>> map (+1) [1, 2, 3]
   [2,3,4]
   

   >>> map id [1, 2, 3]
   [1,2,3]
   

   >>> map (\n -> 3 * n + 1) [1, 2, 3]
   [4,7,10]
   

5. map :: (a -> b) -> [a] -> [b]

   base	Data.List

   map f xs is the list obtained by applying f to each element of xs, i.e.,

   map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
   map f [x1, x2, ...] == [f x1, f x2, ...]
   

   this means that map id == id

   Examples

   >>> map (+1) [1, 2, 3]
   [2,3,4]
   

   >>> map id [1, 2, 3]
   [1,2,3]
   

   >>> map (\n -> 3 * n + 1) [1, 2, 3]
   [4,7,10]
   

6. map :: (a -> b) -> NonEmpty a -> NonEmpty b

   base	Data.List.NonEmpty

   Map a function over a NonEmpty stream.

7. map :: (a -> b) -> [a] -> [b]

   base	GHC.Base

   map f xs is the list obtained by applying f to each element of xs, i.e.,

   map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
   map f [x1, x2, ...] == [f x1, f x2, ...]
   

   this means that map id == id

   Examples

   >>> map (+1) [1, 2, 3]
   [2,3,4]
   

   >>> map id [1, 2, 3]
   [1,2,3]
   

   >>> map (\n -> 3 * n + 1) [1, 2, 3]
   [4,7,10]
   

8. map :: (a -> b) -> [a] -> [b]

   base	GHC.List

   map f xs is the list obtained by applying f to each element of xs, i.e.,

   map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
   map f [x1, x2, ...] == [f x1, f x2, ...]
   

   this means that map id == id

   Examples

   >>> map (+1) [1, 2, 3]
   [2,3,4]
   

   >>> map id [1, 2, 3]
   [1,2,3]
   

   >>> map (\n -> 3 * n + 1) [1, 2, 3]
   [4,7,10]
   

9. map :: (Word8 -> Word8) -> ByteString -> ByteString

   bytestring	Data.ByteString

   O(n) map f xs is the ByteString obtained by applying f to each element of xs.

10. map :: (Char -> Char) -> ByteString -> ByteString

    bytestring	Data.ByteString.Char8

    O(n) map f xs is the ByteString obtained by applying f to each element of xs
