This is a very sane exercice to do, while obviously not something to recommend for production code - but I guess it's not the point. We often take our tools for granted, without thinking about how they were designed. Doing such exercice allows both to get insights into the possible solutions for a problem one of our tools solves (allowing us to understand our tools better), and also is proper training for architecturing our own tools. Thanks for sharing your discoveries.
