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 function to each element of a Stream, lazily

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]

Generates a map using a Range to determine the length.
*This may fail to generate anything if the keys produced by the*
*generator do not account for a large enough number of unique*
*items to satify the required map size.*

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.
