Vec$VecConcreteExtension<T extends Object> extension
Methods only implemented when T is a concrete type (non-nullable).
Why: Correctness of code and reduces bugs.
e.g. if nth returns null on a nullable iterable, the nth element is
either null or the iterable does not have n elements. While if it returns Option, if the element
is null it returns Some(null) and if it does not have n elements it returns None
