>Much as in C++, this is not really allowed: drop runs during panic unwinding, a panic during a panic will hard-abort the entire program.

Right, I didn't really consider that a "drawback" because I'm in the camp that considers that panic! shouldn't unwind but actually abort the process here and there anyway. But you're right that if you rely on the default unwinding behavior panic!ing in destructors is a very bad idea.

You do rely on the default unwinding behavior anyway at least for `cargo test`: the test framework depends on being able to catch the unwinds from `assert_eq!` and similar.
