There are libraries that do just this like https://effect.website/docs/guides/schema/introduction.

Appreciate the write up though! All too easy to rely on libraries without understanding what's under the hood.

Thanks for sharing, it was a good read.

Using a third-party library when it's applicable definitely works. Much of this post is for those who can't add a heavy dependency :)
