Personally I don't like using with prefix in builders, I was simply presenting an example from another comment. the difference, IMO, is - in Javascript - that this // The style fetch() uses today trig({mode: "cos", typ: "hyperbolic"}) ^^^ would fail silently while // The builder refactor trig().mode("cos").typ("hyperbolic")(val) would trigger a compilation error but, IMO, passing objects is good enough most of the times, and I consider it a much better solution over passing boolean flags
