Thanks for the link to the animations. I want an extremely performant deep copy solution, I've been thinking of using an allocator to implement it. If we have a tree data structure or a nested hashmap, then we want to copy it cheaply, there is copy on write. But most copies of hashmaps are slow because they instantiate every child object in a recursive loop. So I want to be able to memcpy a complicated data structure for cheap copies.
