Even more fun is that you can use the special `end` index to implement a stupid-simple circular index: `A[mod1(i, end)]` will always be in-bounds for integer `i`. It's not a common case, though. Using inclusive ranges and 1-based indexing makes Julia's slicing syntax use first-class ranges that can behave like arrays themselves. You can do math on them. You can do all sorts of amazing things that make your life easier: https://julialang.org/blog/2016/02/iteration https://julialang.org/blog/2016/02/iteration Sometimes you want to count fenceposts, and sometimes you want the distance (e.g., offset) from the first post. Keep this imagery in mind and it's easy to do either in any language.
