Ah, thanks. I didn't know DRY has an antonym - WET. I followed the link and saw that this behavior is also called copy-and-paste programming. I think I'll use this one from now on. Wikipedia has a funny animation for that.

Except DRY is not about not repeating code at all. It's about having a single source of truth. I'm not saying this is the case here, but it's a problematic misconception because it encourages pre-emptive optimization of repetitions that can be purely coincidental and not rooted in business requirements.

Write Every Time fits. I like this.
