I'm glad that I provide amusement, but rustc-1.63.0 still compiles this program that panics at runtime. My experience with Rust is 5 min, so the style may provide further amusement:

  fn f(n : usize) -> usize {
    if n == 0 {
      10
    } else if n % 32327 == 0 {
      1
    }
    else {
      f(n-1)
    }
  }

  fn main() {
    let a = [1,2,3,4,5];
    let n = f(12312);
    println!("{:?}", a[n]);
  }
