It’s worth considering what Andrew Kelley says in this talk:
It’s my goal and it’s still my goal to not get carried away, like, adding a lot of stuff. There’s a lot of features that are not in Zig and that’s very intentional, and it’s hard because, you know, everyone likes to propose features and it’s really easy to make fun of C++, but everyone has that one feature from C++ that they like and want to put it in in your language, they want to put it in Zig, and if everyone had their favorite feature from C++ in Zig it would just be C++. But I’m not gonna let that happen
(there was a similar sentiment expressed in the Q&A of this older talk as well)
