lens - more than a curiosity
Lenses are a simple but very useful construct that provide views
over data for retrieval and modification in a compositional way.
The `lens` library in haskell (a.k.a. Control.Lens) takes this idea
to an extreme. This talk will provide a bit of a history around
lens encodings, and then attempt to demonstrate that `lens` should be
an essential part of any haskellers toolkit, and not just a curiosity,
or nice toy.
