Immutable data structures
-------------------------

[](#immutable-data-structures)

Persistent data structured, not optimized for big collections/arrays

All collection are typed, extend from the base type, set the allowed type by overriding `abstract public function type(): string;`, return must the desired type classname.

When a getter operation would produce a mutation, a two elements array is returned, the first element would be the modified collection, and the second one the got element.

```
$queue = Queue::fromArray([1, 2]);

```
