//@ run-rustfix

// Regression test for https://github.com/rust-lang/rust/issues/144319.
// Function-local constructors cannot be named through the enclosing function
// path. The suggestion must omit path segments that cannot be written in source,
// while preserving real path segments like local modules and enums.
