I’m curious, has anyone here had an actual need for genetics in production code? I mean, like you actually have an uncountable or at least large number of types that you want to push through a generic mechanism? I use “generics” in TypeScript but it’s always a very small number of types: usually two, maybe up to 10... There’s no reason I couldn’t do that without generics, just by writing a couple line plugin for each type that converts it to a common representation. I’m not convinced that’s even strictly worse than generics from a usability perspective.
