[Idea] Use Collections instead of default arrays

[NoelDavies]

I know that it requires another dependency, but what is people's thoughts on using Collections over vanilla arrays for a lot of what's being used currently.

I personally think it would make things a lot cleaner and easier to read, use and understand.

If you're referring to https://www.php.net/manual/en/class.ds-collection.php, then that would require everybody to install the ds extension, which would definitely be a breaking change. It would be wiser to stick with vanilla arrays so more people can actually use this library.
