Interesting idea. I am not sure that such is available in Go. In Go, with slices, once the backing array has been allocated, I don’t think you can deallocate some at the end of it. But I might be wrong. There is a difference in Go’s slices between length and capacity. Length is the number of elements in the slice, and capacity is the number of elements that can fit in the backing array (so len <= cap).
