Post #2162173

@totbwf In the early 2000s we did a project a bit like that for live content conversion - everything was a dependency relationship defined by a rule, and we had “meta-rules” that could emit more rules as output. So the “root rule” of the system was fixed, but everything else could change dynamically and the minimal set of necessary changes would propagate. I’ve used that pattern a few times since for build systems and it works pretty well once you get the dependency engine implemented.
