One of the most mindboggling thing about the recurrent 0- vs 1-based indexing discussion is how incredibly rarely that difference is ever used programmatically in Julia. Most of the large julia packages are programmed in a way that doesn't care whether the array is 0 or 1 based. It is important in some other languages, and then I just think people are happy that this is something that everybody can agree to disagree on. I don't think the discussion is very productive though.
