I understand that, and as a developer, I'm used to working with stuff like this.
However, without some sort of interactive IDE, this just feels like magic numbers. The code itself, as written, is not enough to help you visualize what you are producing.
Remember, just because you 'don't see how this kind of code is helpful for design' it doesn't mean that other people share your view. We all see things differently - a good thing to remember especially in these times.
