Three flavors of sorting Go slices

There are primarily three ways of sorting slices in Go. Early on, we had the verbose but flexible method of implementing sort.Interface to sort the elements in a slice. Later, Go 1.8 introduced sort.Slice to reduce boilerplate with inline comparison functions. Most recently, Go 1...
