Question 14 triggers non_local_definitions warning in 1.83-nightly (again)

    warning: non-local `impl` definition, `impl` blocks should be written at the same level as their item
      --> questions/014-trait-autoref.rs:20:13
       |
    11 | fn main() {
       | --------- move the `impl` block outside of this function `main`
    ...
    20 |             impl Trait for char {
       |             ^^^^^-----^^^^^^^^^
       |                  |
       |                  `Trait` is not local
       |
       = note: an `impl` is never scoped, even when it is nested inside an item, as it may impact type checking outside of that item, which can be the case if neither the trait or the self type are at the same nesting level as the `impl`
       = note: this lint may become deny-by-default in the edition 2024 and higher, see the tracking issue <rust-lang/rust#120363>
       = note: `#[warn(non_local_definitions)]` on by default

An earlier iteration of this warning previously appeared in 1.79-nightly
but was reverted.
