I switched from objective-c to swift thinking job done, and felt like I was learning a new language with each new version. I ended up switching back to objective-c.
I think Java had a good start by defining a solid language spec (JLS) up front, which was a bible during the rapid standard library expansion days, but the JVM stayed stable at least.
I left Golang behind because of the same academic churn in language design that I saw in Swift.
So at the moment I really love coding in Zig. It already does everything I need it too already, and anyway I cant upgrade past 0.8.1 because 'old mac', and wont run on Asahi M1 because 'new mac'. But I assume in trying to be a good C replacement, these are temporary limitations, especially now it can self compile.
What I really enjoy is that I can use it for very lightweight WASM / web front-end stuff, and at the other end of the client scale, I am using it for some SOC programming on the PinePhone. I know C has the same reach, but my days of looking up ** semantics in K&R are long past!
Hopefully we'll get a solid language spec soon, and the language changes will slow to a crawl once 1.0 approaches. As for the lacking documentation that is always a complaint, I'll hopefully try to contribute to that when I start my new Zig project in May.
Anyway respect and thanks to Andrew and the team for all the hard work they are doing. It is an amazing project and I hope it works out.
