>>>import Control.Lens
newtype ReifiedLens s t a b Source
Reify a Lens so it can be stored safely in a container.
type ReifiedLens' s a = ReifiedLens s s a aSource
typeReifiedLens'=SimpleReifiedLens
newtype ReifiedIndexedLens i s t a b Source
Reify an IndexedLens so it can be stored safely in a container.

newtype ReifiedIndexedTraversal i s t a b Source
Reify an IndexedTraversal so it can be stored safely in a container.

type ReifiedIndexedTraversal' i s a = ReifiedIndexedTraversal i s s a aSource
typeReifiedIndexedTraversal'i =Simple(ReifiedIndexedTraversali)
newtype ReifiedTraversal s t a b Source
A form of Traversal that can be stored monomorphically in a container.
Constructors
| Traversal | |
Fields

type ReifiedTraversal' s a = ReifiedTraversal s s a aSource
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)
Instances
newtype ReifiedIndexedGetter i s a Source
Reify an IndexedGetter so it can be stored safely in a container.
Constructors

Instances
| Representable (ReifiedIndexedGetter i) | |
| Strong (ReifiedIndexedGetter i) | |
| Profunctor (ReifiedIndexedGetter i) | |
| Functor (ReifiedIndexedGetter i s) | |
| Semigroup i => Apply (ReifiedIndexedGetter i s) |
newtype ReifiedFold s a Source
Reify a Fold so it can be stored safely in a container.
This can also be useful for creatively combining folds as
ReifiedFold sReaderT s [] and provides similar
instances.
>>>("hello","world")^..runFold ((,) <$> Fold _2 <*> Fold both)[("world","hello"),("world","world")]
