Users frustrated at the lack of a `merge` in Swift want it to be opinionated and "just do the right thing," i.e., the same way as whatever other language they most recently used. A properly annotated and indented-to-be-beautiful use of the closure-based version will take up the same amount of code as doing the merge by hand with your custom condition.
