title: sorting a uint64 slice in go
body: <p>I'm writing Go application using Go 1.7rc3.</p>
  <p>I have a slice of <code>uint64</code> (<code>var dirRange []uint64</code>) that I want to sort.</p>
  <p>The sort package has a function <code>sort.Ints()</code> but it requires <code>[]int</code> and I have <code>[]uint64</code>.</p>
  <p>What do I do? Can I type cast the all slice?</p>
