Ask HN: What do you want to see in a systems programming language?

I am working on a new systems programming language, similar to C++ with syntax that somewhat resembles Go or LLVM in some ways. While it isnt quite ready (at least a month away from alpha release), I am curious what features are the most desired in a systems programming language. I'd like to get inspiration for new language features. Pain points with C++, Rust, C, Zig etc.. What you like, don't like, etc.
