> DRY paints that as a feature That's not what DRY should be. Good developers should understand at least a couple of levels of abstraction underneath what they're writing in order to produce sensible code. The idea of abstraction is that you only have to spend the afternoon/day/week (depending on the complexity that's being abstracted over) learning how everything comes together once, as opposed to spending that time to grok a slightly different version of the same complex system every time you read/write something new.
