  Pattern matching syntax for ECMAScript

  

Hopefully we will get real pattern-matching at some point (https://github.com/tc39/proposal-pattern-matching), but I kinda sorta like this!

  Runtime type system for IO decoding/encoding

Sure, if you're validating some data there're loads of better ways to do it than a bunch of conditionals. I was purely commenting on the switch(true) pattern vs some "if"s.

That approach looks nice though. On that subject, JS has some nice libraries including io-ts[1] which has a functional approach using Eithers to encapsulate errors/success.

I've never considered writing a proposal for a language feature before, but after 2 minutes of googling, this actually looks completely doable:

So, impostor syndrome aside, why not? Wanna team up on that?
