I never thought about this until now, but I guess it's actually super weird that ArrayList doesn't expose a getter-by-index and an iterator and instead expects you to use .items.
The thing is... Every function in the std works with slices, not woth array lists. You pass slices to mem.tokenize(), you pass alices to mem.cmp(), you pass a slice to sort().
I think that's why ArrayList exposes it for you, so you can just use it as a regular slice everywhere. I, honestly, find that simple and liberating. I'm glad there's no other kind of accessor thing.
Continuous memory is just fast, and if you have some first class support for working with it, it makes no sense to duplicate the api. But again, if you want a hashmap you don't get the slice, for the slice doesn't make sense there...
