You can achieve type safety with collections like:
interface CustomerCollectionInterface extends ArrayAccess, IteratorAggregate { public function addCustomer(Customer $customer); public function offsetGet($offset): Customer; }

I find this approach much cleaner.

Well, yeah, it depends if the collection itself has some special logic on its own (then it makes sense to create a class for it), otherwise, maybe it would be a bit overkill to create a new collection class for each collection type, don't you think?

I strongly disagree, but that is a matter of opinion. I prefer that things fail immediately, when I want to add wrong item somewhere and not when I want to consume the value.

I miss typed lists (collections) as a language feature though. So both approaches are a workaround.
