// FIXME(#54943) This test targets the scenario where proving the WF requirements requires
|
|
// knowing the value of the `_` type present in the user type annotation - unfortunately, figuring
|
|
// out the value of that `_` requires type-checking the surrounding code, but that code is dead,
|
|
// so our NLL region checker doesn't have access to it. This test should actually fail to compile.
