I was reading the Swift programming book published by Apple, and in the closures chapter, I came across a series of code snippets. The snippets relate to the closure expression syntax used in Swift, but that is not important for the purpose of this post. Putting aside the programmer perspective (code readability etc. etc.), let's just focus on the aesthetics of the collection. Each iteration does away with a seemingly 'necessary' element, and only through this process does it arrive at the bare essentials.
Although these are just snippets of code, the process of iterating, evaluating and doing away with the unnecessary applies to all aspect of our lives.
