Pickler combinators as provided from the paper of A. Kennedy (https://goo.gl/BoLjrj) [Scala picklers](https://github.com/scala/pickling) are an extension of this idea, with support for OO ([paper](https://infoscience.epfl.ch/record/187787/files/oopsla-pickling_1.pdf) for its design) This second part looks into compressing stream by increasing sharing It's really all about *simple functions*, so applies to most functional languages, as evidenced by the various implementations of this idea in different languages like #haskell #ocaml #scala #picklers #fsharp Comments (positive or negative) on the video, code, concepts, welcome !
