This is a great place to bring up "terms of art", again. When looking to other languages as our muse, trying to adapt syntax into Swift's tortured guidance system is less successful than retaining those terms, which have already been extensively bikeshedded in their original development. I much prefer takeWhile dropWhile, etc.
