error[E0005]: refutable pattern in local binding: `&_` not covered
 --> /home/runner/work/glacier/glacier/ices/78174.rs:5:9
  |
5 |     let const { "foo" } = "foo";
  |         ^^^^^^^^^^^^^^^ pattern `&_` not covered
  |
  = note: `let` bindings require an "irrefutable pattern", like a `struct` or an `enum` with only one variant
  = note: for more information, visit https://doc.rust-lang.org/book/ch18-02-refutability.html
  = note: the matched value is of type `&str`
help: you might want to use `if let` to ignore the variant that isn't matched

5 |     if let const { "foo" } = "foo" { /* */ }
