Indexing tuple warning misleading

The following rust snippet:

fn main() {
  let x = (0u32, 1u64, 2isize);
  for i in 0..3 {
      println!("{}\n", x[i]);
      // ERROR: to access tuple elements, 
      // use tuple indexing syntax (e.g. `tuple.0`)
      // println!("{}\n", x.i); // This doesn't obviously work
  }
}

produces a warning that recommends using .0 to index the tuple, but what it should recommend is to match on the index.

1. Current output:

   error[E0608]: cannot index into a value of type `(u32, u64, isize)`
    --> src/main.rs:4:24
     |
   4 |       println!("{}\n", x[i]);
     |                        ^^^^
     |
     = help: to access tuple elements, use tuple indexing syntax (e.g., `tuple.0`)
