error[E0282]: type annotations needed for `[usize; _]`
  --> $DIR/issue-83606.rs:8:13

LL |     let _ = foo("foo"); //<- Do not suggest `foo::<N>("foo");`!
   |         -   ^^^ cannot infer the value of const parameter `N` declared on the function `foo`
   |         |
   |         consider giving this pattern the explicit type `[usize; _]`, where the type parameter `N` is specified
