title: Julia: How to obtain the Array pointed at by pointer?
body: <pre><code>a = [1,2,3]
  ap = pointer(ap)
  </code></pre>
  
  <p>Suppose, I am only given <code>ap</code>, how do I get back a <code>Vector{Int}</code> that the pointer <code>AP</code> was pointing at without using <code>unsafe_load</code>?</p>
