Introduction to lenses in Haskell

This time Adam Szlachta will give a brief introduction to lenses in Haskell. They are pretty standard and very widespread technique we can't imagine living without. But since they are provided by an external complex library they're often omitted by Haskell tutorials and introductory books. Basic lenses usage is really simple and they make the haskellers live much easier. We will focus on practical aspects in this talk.
