Map a function over all values in the map.
```map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]
```
map f s is the set obtained by applying f to each element of s. It's worth noting that the size of the result may be smaller if, for some (x,y), x /= y && f x == f y
Map a function over all values in the map.
```map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]
```

O(n) map f xs is the ShortByteString obtained by applying f to each element of xs.
O(n) map f xs is the ShortByteString obtained by applying f to each element of xs.
Map a function over all values in the map.
O(n) Map a function over a vector.
Map a function over a Bundle
O(n) Map a function over a vector.

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
Transform the original string-like value but keep it case insensitive.
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
```
Map a function over a NonEmpty stream.
