The “ghost cells” link [above](https://discourse.julialang.org/t/a-better-way-to-chose-a-random-neighbor/80979/2) has an example. [Here](https://discourse.julialang.org/t/seemingly-unnecessary-allocation-within-for-loop/72556/8) is another example, and [here](https://discourse.julialang.org/t/speed-up-multidimensional-code-without-base-cartesian/68328/14) is another.
