D and Nim have had the same features for years btw.

Check out Nimony effectively Nim 3.0 from the author. It's a top to bottom rethinking of Nim with all the lessons learned. I'm so hyped about it tbh
It’s pretty obvious why they didn’t, they’re GC by default. That’s already enough to put people off, even if it’s “not a problem” in reality, people will just avoid it for systems programming if they hear that, they will assume all the good features need the GC
I like both of those, I like the idea of Zig, it does seem to be striving to be pure in some areas where C is "king" that other languages gloss over, but Zig is always changing, and its got some elitist people in its ranks that left me not wanting to bother with it. Imagine a programming language maintained and used by geohot clones.
God I loved playing around with D back in the day when I was in high school. It seemed like a no-brainer that it was going to be huge. It's such a shame it never took off. Incredible language.
