+//! This test ensures that `#[track_caller]` can be applied directly to diverging functions, as
+//! the tracking issue says: https://github.com/rust-lang/rust/issues/47809#issue-292138490.
+//! Because the annotated function must diverge and a panic keeps that faster than an infinite loop,
+//! we don't inspect the location returned -- it would be difficult to distinguish between the
+//! explicit panic and a failed assertion. That it compiles and runs is enough for this one.
