Well I am impressed. And I am very glad to see more and more languages in this space. I particularly like that Zig seems to be minimalistic -- a lot more fun to look at (for me) than C++ or Rust. But I didn't see anything in Zig similar to Rust's lifetimes. Well it's nice to be rid of that complexity, but I don't see how you are going to do C-like pointer stuff safely without them. Can anyone explain what these languages (e.g. Zig, Myrddin, Nim) do instead?
