-// Test taking the LUB of two function types that are not equatable but where
-// one is more general than the other. Test the case where the more general type
-// (`x`) is the second match arm specifically.
-//
-// FIXME(#73154) Pure NLL checker without leak check accepts this test.
-// (Note that it still errors in old-lub-glb-hr-noteq1.rs). What happens
-// is that, due to the ordering of the match arms, we pick the correct "more
-// general" fn type, and we ignore the errors from the non-NLL type checker that
-// requires equality. The NLL type checker only requires a subtyping
-// relationship, and that holds. To unblock landing NLL - and ensure that we can
-// choose to make this always in error in the future - we perform the leak check
-// after coercing a function pointer.
