// This test is meant to test that we can have a stable item in an unstable module, and that
// calling that item through the unstable module is unstable, but that re-exporting it from another
// crate in a stable module is fine.
//
// This is necessary to support moving items from `std` into `core` or `alloc` unstably while still
// exporting the original stable interface in `std`, such as moving `Error` into `core`.
