Description
Programs like this are confusing to run on the playground because they print a panic message, but actually exit successfully:
fn unwind() {
panic!();
}
fn main() {
std::panic::catch_unwind(|| unwind()).unwrap_err();
}
It would be good to have some way to see the exit status of the program on playground, to tell whether the program (thinks it) ran successfully or failed.

Reproduce the Rust example in the playground and inspect how program output and execution results are presented. Add a visible exit status for runs, including this successful panic-catching case, and verify that users can distinguish successful and failed execution.
