Transform this map by applying a function to every value.

Transform this set by applying a function to every value.
The resulting set may be smaller than the source.

>>> HashSet.map show (HashSet.fromList [1,2,3]) HashSet.fromList ["1","2","3"]

Apply a transformation to all values in a stream.
Subject to fusion

Apply a transformation to all values in a stream.
Subject to fusion
Since 0.3.0

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, ...]

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

Apply a function to all values flowing downstream

map id = cat map (g . f) = map f >-> map g

toNonEmpty (mapf xs) = map f (toNonEmpty xs)

Map a function over a NonEmpty stream.

Maps a pure function over an InputStream.
`map f s` passes all output from `s` through the
function `f`.
Satisfies the following laws:

Streams.map (g . f) === Streams.map f >=> Streams.map g Streams.map id === Streams.makeInputStream . Streams.read

map `f xs` is the list obtained by
applying `f` to each element of `xs`, i.e.,
`map id == id`
**Examples**

map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn] map f [x1, x2, ...] == [f x1, f x2, ...]this means that

>>> 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]
