Andreas Kling (of SerenityOS and Ladybird fame) streamed contributing a performance improvement to this compiler that was pretty interesting to watch: https://www.youtube.com/watch?v=b4PZgvPYkP4

For those asking what’s the point, check the author’s GitHub profile: “I’m also making my own Ruby called Natalie. You know, for fun!”.

Very cool. Ruby is still my favorite lang after many....

Wouldn't it be easier to have it transpile to Crystal? The languages are already extremely similar

I might port some of my algorithms to this!

What's the goal of the project? It's not clear from the Github repo or the site (natalie-lang.org).

It's a cool project, but I'm not really sure what the point is. I'm doubtful that you could ever match the full expressiveness of Ruby in C++ or any compiled language. If you wanna play with it because it's fun, that's fine, but I doubt that it would ever be able to do much with most of the Ruby code out there.
