ts-pattern has been a decent band-aid for the lack of native pattern matching, but obviously has downsides that could be avoided if it was built into the language.

Project mention: Show HN: Next-token prediction in JavaScript – build fast LLMs from scratch | news.ycombinator.com | 2024-04-10This is awesome, thanks. I've been messing with wink's NLP library (https://winkjs.org/wink-nlp/) to transform user queries and format responses so I can make a proper chat bot - will see what I can learn from these!
Author of other.nvim here, thanks for the mention :)
I've used it. :)

Project mention: Removing Garbage Collection from the Rust Language (2013) | news.ycombinator.com | 2023-09-11This comment is misleading &| misinformed.
Sum types are built-in [1] for formal parameters. `nil` is only for `ref|ptr` types. In much code you can just use stack allocated value types and there is neither GC concern nor nil concern, but there is also a mode to help: https://nim-lang.github.io/Nim/manual_experimental_strictnot...
Nim has an easy-ish to use Lisp-like syntax macro system where you just receive & process an AST. So, to do the rest you can make libraries adding the feature without relying upon upstream compiler: such as https://github.com/beef331/sumtypes for variables with sum types or pattern matching libs like https://andreaferretti.github.io/patty/ | https://github.com/alehander92/gara.
Project mention: The Sage Compiler, Operating System, and Web-Demonstration | news.ycombinator.com | 2024-01-02Hello, yes, I'll go back and add some text examples as well.
I put all the example programs in text on the web-demo, though, if you want to see more there! You can copy, read, or modify them there!
