I really wish Zig had followed Rust’s lead and made variables const by default :/

  Variables are immutable by default in Rust, but they're not const by default. The difference is that a variable can become mutable while a const is always immutable.

    How do you set a variable as mutable after the fact in rust?
    • nicoburns 5y ago
      You can do: let foo = "1234".to_string(); let mut foo = foo; foo = "5678"; This only works if you have ownership of the variable though. And in practice it's a pretty good compromise, because it's pretty hard to do this by mistake. Note: const in rust is different to const in some other languages: it represents a value that is duplicated inline into each use site at compile time.

        Yes I think i see it more like constexpr.
