Description
Description
The reason why a loop will never actually complete isn't always obvious (see #16054 for an example). For such cases it would be nice to have a note pointing out all the locations where this occurs. Obvious causes ideally wouldn't get any additional output.
Examples
loop {
do_something();
// No need to point this out.
panic!();
}
// Imagine something less obvious.
let x = || Some(panic!());
loop {
// Why doesn't this loop?
x().unwrap();
}
