Read the whole engine in an afternoon, with no magic hidden anywhere you can't follow it. - Hackable. Set a breakpoint on any line, change it, rerun, all on your own machine. It genuinely works, which makes this a living reference rather than a diagram. - The gaps are the point. It deliberately keeps only the minimal core; what's missing isn't half-finished, it's where you branch off and make it your own.
