      functional programmers! what are some of your favorite data structures? what wild, weird, exotic things have you seen and been fascinated by? for me, i’m especially in love with zippers/tubes/derivatives, and also with memotries 💜

      not so much a data structure as a way of generalizing over computations consuming or producing same, but recursion schemes are really cool

      The short version of the pitch is this: "just as using while and for loops rather than goto brings structure and harmony to imperative control flow, the use of recursion schemes over hand-written brings similar structure to recursive computations"

      There's a great ~4 part intro/deep dive starting here, not sure if I can explain it well in a tweet quite yet but basically the idea is to abstract over the actual recursion such that you just need to provide a fn that does one 'layer' of the fold/unfoldhttps://blog.sumtypeofway.com/an-introduction-to-recursion-schemes/ …

          oh yes, recursion generally speaking are neat :) it took me ages to understand foldr, and i think i only succeeded once i learned about Fix/Mu types

          If you understand those types you should be able to pick up recursion schemes pretty quickly

          yeah i figured it all out a few years ago after struggling for a while :p the relationship of mu types to other things is really cool too

          things that I'm a huge fan of lately: extensible effects (cc @rob_rix), streaming libraries like `machines`, and building EDSLs with generalized algebraic data types and interpreters! the latter especially is changing how I approach problems
