Is it me, or is the recommendation of adding a level of abstraction less readable than the “bad” example using “by_size_and_color?” Additionally, another example of a developer coming in and making it more extensible when that is not the requirement 80% of the time.

However, I’ve attempted to keep up with its development since my hobby game development years in my teens.
