While these regex patterns are nice for accepting anything that we'd expect to output, it also makes the test kinda weak - we could start outputting different wrong addresses (and bitwidth sizes), without the test catching it - that's not ideal. So I think it would be good to check the actual numbers as well, to make sure the test catches any potential breakage in it.
