title: What's C++'s `using` equivalent in golang
body: <p>What's C++'s <code>using some_namespace::object</code> equivalent in golang?</p>
  
  <p>According to the question <a href="https://stackoverflow.com/questions/12925450/importing-packages-in-go">here</a> 
  I can get <code>using namespace common</code> with statement below:</p>
  
  <pre><code>import (
    . "common"
  )
  </code></pre>
  
  <p>But this would import the entire namespace. Right now I only want to use, say <code>platform</code> definition, something like <code>using common::platform</code></p>
  
  <p>Is there an equivalent for this in Go, so that I don't have to type <code>common.platform</code> all the time?</p>
