Is there some advantage to this over

    try:
        os.unlink('missing.txt')
    except OSError as exc:
        do_something()

I thought the whole point was to replace code that would otherwise
contain 'except: pass' with something slightly more concise. Once you
expose the exception, it becomes just an uglier version of a try/except
block, as far as I can see.
