Could you refer to a specific revision of the specification you used to implement
so that we know exactly what the reference point was should the spec change in the future.

It seems strange to repeat this code given shape and box cannot appear twice.
I would refer an approach where we have a loop and guarantee that we run it at most twice,
and making sure that shape & box are parsed at most once.
