Most languages don't have a definition of "slice" at all.

It's not broken, it's just fast and simple. But yes, it does require you to know that Go's slices are not exactly Python's lists (which do gratuitous copies). Java's implementation does an insert on the original list (both surprising and an unnecessary copy).
