If you find yourself iterating over a group of structs like this a lot (especially if there's a lot of them to iterate over), you might want to consider measuring the performance differences between []*Person or []Person. With pointers, the actual structs might be far away from each other in memory, which may prevent you from taking full advantage of your processor's cache since it won't be able to benefit from the spatial locality that an array (or slice) offers.
