A simple but powerful implementation of function lenses (aka functional references, accessors, etc..). <br><br>This library provides a convenient way to access and update the elements of a structure. It is very similar to Data.Accessors, but simpler, a bit more generic and has fewer dependencies. I particularly like how cleanly it handles nested structures in state monads. It also contains a couple simple functions that can be used to easily convert a function that fetches data from a structure to a function that modifies data in the structure.<br>
<br>Hackage hasn&#39;t generated the haddock documentation yet, but there is a mini-tutorial in Data.Lenses that explains it&#39;s use.<br>Also for those that are interested it&#39;s also hosted on github here: <a href="http://github.com/jvranish/Lenses/tree/master">http://github.com/jvranish/Lenses/tree/master</a><br>
