Disequilibrium -- surprises, failures, jokes, and disorientations -- will always happen. Taking that opportunity to move away from a local maximum towards a global maximum is up to me.
Somewhere along the way, programmers learn the “DRY” principle: Don’t Repeat Yourself. This is good advice, within reason. But if you wring every bit of redundancy out of your code, you end up with something like Huffman encoded source. In fact, DRY is very much a compression algorithm. In moderation, it makes code easier to maintain. But carried too far, it makes reading your code like reading a zip file. Sometimes a little redundancy makes code much easier to read and maintain.
