-// This test verifies that never type fallback preserves the following code in a
-// compiling state. This pattern is fairly common in the wild, notably seen in
-// wasmtime v0.16. Typically this is some closure wrapper that expects a
-// collection of 'known' signatures, and -> ! is not included in that set.
-//
-// This test is specifically targeted by the unit type fallback when
-// encountering a set of obligations like `?T: Foo` and `Trait::Projection =
-// ?T`. In the code below, these are `R: Bar` and `Fn::Output = R`.
