+error[E0005]: refutable pattern in local binding
+  --> $DIR/feature-gate-exhaustive-patterns.rs:8:9
+   |
+LL |     let Ok(_x) = foo();
+   |         ^^^^^^ pattern `Err(_)` 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 `Result<u32, !>`
+help: you might want to use `let else` to handle the variant that isn't matched
