Not necessarily wrong. You’re probably doing the same work at runtime. That might be either just as good (a subjective preference) or more correct (for certain kinds of dynamism) depending on context. In some cases, there are clear static invariants that could be guaranteed at compile time, and some folks will be more inclined to squeeze as much out of that as possible. In my experience, the benefits of that vary wildly from “total waste of time” to “solves a recurring and expensive problem for good”, with a lot in between.
