Map a function over all values in the map.

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.
Combinator for the <map> element. Example:
```map \$ span \$ toHtml "foo"
```
Result:
```<map><span>foo</span></map>
```
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
```
map f xs is the DList obtained by applying f to each element of xs. [itex](length (toList xs)). map obeys the law:
```toList (map f xs) = map f (toList xs)
```
map f xs is the DNonEmpty obtained by applying f to each element of xs. [itex](length (toNonEmpty xs)). map obeys the law:
```toNonEmpty (map f xs) = map f (toNonEmpty xs)
```
Map a function over a NonEmpty stream.
