* Add LinkedList Operators and Update Tests * add linkedlist printing and `@new` macros (single-line init and pool-capable) * add linkedlist node and reg iterator; comparisons w/ == * Fix benchmarks. Drop random access to the linked list using []. Only return a direct array view. --------- Co-authored-by: Christoffer Lerno <christoffer@aegik.com>
