> The highest up on my wish list would be that - as I understand it - you can not currently exit the process cleanly (EDIT: early) with a non-zero exit code in stable rust.

You don't need any fancy features to do this. Every single one of my Rust CLI programs has done this on stable Rust for years. All you need to do is bubble your errors up to main.

If you have destructors that you want to run, then put those in a function that isn't main.

I would not consider setting an exit code to be a fancy feature, but I guess we are living on the bleeding edge here :)

EDIT: I should have said explicitly in my initial comment that I knew about std::process::exit and panic!, but did not consider them to be a clean solution for exiting the program under normal circumstance -- more of an abort() mechanism.

I don't see why. process::exit is perfectly clean from my perspective. You don't need to be on the bleeding edge. This has been possible since Rust 1.0.
