Poor error message when indexing result of dbg!()

[JustAPerson]

Consider:

fn main() {
  dbg!(1, 3)[1];
}

On nightly (2020-02-05) this yields the error:

error[E0608]: cannot index into a value of type `({integer}, {integer})`
 --> src/main.rs:2:3
  |
2 |   dbg!(1, 3)[1];
  |   ^^^^^^^^^^^^^ help: to access tuple elements, use: `($ ($ crate :: dbg ! ($ val)), +,).1`

Maybe the help: to access tuple elements, use part should either avoid printing the left-hand side of the dot operator, or use the span of the source file like help: to access tuple elements, use: 'dbg!(1, 3).1'

Message is different now:

error[E0608]: cannot index into a value of type `({integer}, {integer})`
 --> src/main.rs:2:3
  |
2 |   dbg!(1, 3)[1];
  |   ^^^^^^^^^^^^^

  = help: to access tuple elements, use tuple indexing syntax (e.g., `tuple.0`)
