Go(lang): Robust generic functions on slices

>>signa1+(OP)
The problems with the API they point out are almost all things that rust's ownership system was built to solve.

Things like:

    slices.Sort(s) // correct
    slices.Compact(s) // incorrect
    slices.Delete(s, ...) // incorrect
    s := slices.Delete(s, ...) // incorrect if 's' is referenced again in the outer scope
    s = slices.Delete(s, ...) // correct

All of those are solved by having functions like 'slices.Sort' take a '&mut' reference in rust speak, and having 'slices.Compact' and 'Delete' take an owned slice, and return a new owned slice.

Long before that, the problems with the API are solved by having a separate heap type for length manipulations rather than confusing the interfaces.

If Delete or Compact are only available there and it’s modified in place, the problems don’t arise in the first place.
