Mathematical notation is almost always 1 based. Let $v = 1 \dots n$, that sort of thing. So I find translating mathematics into code (which I seem to do quite frequently) much easier with 1 based indexing. (One exception being if you have a lot of modulo arithmetic.) I've used both 0 based (python, C++), and 1 based (R, matlab, mathematica), but I really belive 1 based is the right choice for Julia. It isn't necessary, but it feels better.
