Fairly pleasant in Zig, through abuse of @fieldParentPointer and a pinch of comptime.

It was a little nicer in the `usingnamespace` days. So it goes.

An "etc" worth mentioning specifically is a memory pool: they're useful for any same-sized struct which gets recycled a lot, but for linked lists there are further advantages. You don't have to cast the object to bytes and declare a link pointer, since it already has one: not really an advantage, casting is free, but: if you can arrange to give both sides of the list back, then recycling can be done on a per-list level by prepending the whole thing to the freelist.
