It isn't just about being lazy. I'd argue that the foreach that exists in a couple of Prologs is not declarative (despite being called logical loops etc.) but I still use it because I prefer that over repeating myself. Repeated clauses as OR gets pretty cumbersome once you work with bigger codebases because it sort of violates DRY. If you change/refactor something...suddenly you have to wade through a bunch of clauses. I've rewritten quite a few of these by falling back on imperative code.
