Discovered Zig today. There is some bullshit from its promoter e.g.
https://andrewkelley.me/post/zig-already-more-knowable-than-c.html (especially not fond of forcing array index to be unsigned) and he disses recursion without mentioning tail-call optimization but at first glance it is looking interesting as a replacement for C.
D ``better C'' mode looks good too.
JAI looks nice but it currently is the Cartmanland of programming languages.
My purely prejudiced opinion on Rust is that it looks like a worse Sepples.
