> For a long time I've thought that Don't Repeat Yourself is the most important software engineering rule. It's not. "Don't introduce unnecessary dependencies" and "keep dependency graph without cycles", "keep things modular" and "all operations in a unit (function, module, ...) should be from the same abstraction level" are just as important, if not more, but they're a little more high-level, and thus less actionable. DRY is just simple to enforce, that's all to it.
