//| if you register ``A``, ``B``, and ``C``, they will be run in the order ``C``, ``B``, ``A``.

//|
//| Any optional arguments that are to be passed to func must be passed as arguments to `register()`.
//| It is possible to register the same function and arguments more than once.
//|
//| At normal program termination (for instance, if `sys.exit()` is called or the vm execution completes),
//| all functions registered are called in last in, first out order.
//|
//| If an exception is raised during execution of the exit handler,
//| a traceback is printed (unless `SystemExit` is raised) and the execution stops.
//|
//| This function returns func, which makes it possible to use it as a decorator.
