title: Correct structure for json unmarshal
body: <p>I can't figure out how to build a structure for this json object in golang:</p>
  
  <pre><code>{
      "response": [1702487, {
              "uid": 150261846,
              "first_name": "Олег",
              "last_name": "Брейн"
          }, {
              "uid": 53260546,
              "first_name": "Олег",
              "last_name": "Лобацевич"
          }
      ]
  }
  </code></pre>
  
  <p>As you can see there is no keys names for array and for count too.</p>
  
  <p>Would be glad if you can help</p>
