This is a very deliberate stylistic choice. Compare: "People have, at this point in time, exactly one official name." <-- phrase is false "There exist at least some people who will, at at least some instants in time, have either zero or two or more official names." <-- phrase is true Now multiply that sort of circumlocution by 40. I frequently receive the feedback "I wish you had identified a solution", which suggests to me maybe I missed the opportunity to title the post "Names are intractable hard and any programmer who thinks their program has solved them is wrong." I thought that was pretty explicit in the first paragraph but people seem to really WANT this problem to have a Ruby gem available such that they don't have to worry about it. I want dragons, but will live with my disappointment.
