newtype ReifiedTraversal s t a b Source #
A form of Traversal

type ReifiedTraversal' s a = ReifiedTraversal s s a a Source #
newtype ReifiedGetter s a Source #
Reify a Getter
so it can be stored safely in a container.
This can also be useful when combining getters in novel ways, as
ReifiedGetter
is isomorphic to (->)
and provides similar instances.
>>>
("hello","world","!!!")^.runGetter ((,) <$> Getter _2 <*> Getter (_1.to length))
("world",5)

newtype ReifiedFold s a Source #
Reify a Fold

This can also be useful for creatively combining folds as

instances.
>>>
