I once saw an interview with T. Berners-Lee the author of the original, and most subsequent, spec(s) for URLs/URIs (they started with the WWW in RFC 1630 ). When asked if he had regrets he laughed and said (paraphrased to the best of my recall)

Yes. I really wish I hadn't made urls start with a double backslash.
