@cmuratori.bsky.social gives a compelling analysis of OOP. I wrote production code from the late 80s, using C, which was perfect timing, since OOP has only ever been a thought experiment to me. I like ADTs and DUs, and my new C is #fsharp, which does ADTs better than C.

it's a perfectly fine argument to make in isolation, but arguing that *ocaml* of all languages (literally the only language to actually use global type inference) shouldn't have type classes because they hurt *readability* is... something.
