The manual begins to confront ugly consequences, but is upbeat about it

  Empty slices. Consider a slice s[i..j] where s is of length n. A slice from i to j,
  where j = i-1 and i >= 1 produces the empty sequence, even if i = n+1. Thus 1..0 and
  n+1..n and everything in between are legal (empty) slices. Empty
  slices are quite useful in many algorithms. A slice from i to j where j < i - 1 is
  illegal

``quite useful.'' I imagine so.
