// 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.
