// Regression test for #71732, it used to emit incorrect diagnostics, like:
// error[E0283]: type annotations needed
//  --> src/main.rs:5:10

// 5 |         .get(&"key".into())
//   |          ^^^ cannot infer type for struct `String`
//   |
//   = note: cannot satisfy `String: Borrow<_>`
// help: consider specifying the type argument in the method call
//   |
// 5 |         .get::<Q>(&"key".into())
//   |
