I agree with sauoq.

But here's how I usually write the ternary operator when clarity is a goal:

    return
        $status == 0
            ? 0
            : 1;

Yes, it seems unnecessarily expansive for this simple case... but I probably wouldn't do it for this simple case.

I would, and do, do this for situations such as:

    return
        @things = $obj->get_current_list_of_things()
            ? grep /$wanted/, @things
            : $obj->default_things;

    # o.k., it's a contrived example.  gimme a break.

Predicate and two lemmas, each on its own line.
