DRY has become a mantra throughout the industry. Any time repetitive code shows up, DRY gets applied as a cure all. If you even start to question DRYing up a piece of code, you are viewed as a heretic to the entire industry. Ok, maybe it’s not that bad, but many times DRY gets applied without much thought. This careless application of DRY leads to brittle code, making even simple changes scary because they could have a huge ripple effect.

    Does this need to change in ALL places? How do you know? How can you get all places it is used and be certain it has to change in all of them?

    These seem like questions that are equally important and hard to answer regardless of whether you’re using abstractions, although abstractions have a big advantage in that you can find all the sites where they’re used much more easily than you can find all the places where a piece of code is duplicated (or worse yet, duplicated with slight changes).
