| // Test to ensure that we can handle cases where |
| // let statements create no bindings are initialized |
| // using a Place expression |
| // |
| // Note: Currently when feature `capture_disjoint_fields` is enabled |
| // we can't handle such cases. So the test current use `_x` instead of |
| // `_` until the issue is resolved. |
| // Check rust-lang/project-rfc-2229#24 for status. |
