title: C++ template partial explicit instantiation
body: <p>Can we partially instantiate a C++ template explicitly?</p>
  
  <pre><code>template class &lt;typename T, int N&gt;
  class MyClass {
    ...
  };
  
  template&lt;int N&gt; class MyClass&lt;int, N&gt;;  // not meant for specification
  template&lt;int N&gt; class MyClass&lt;float, N&gt;;
  </code></pre>
  
  <p>just like we can have:</p>
  
  <pre><code>template class &lt;typename T&gt;
  class MyClass {
    ...
  };
  
  template class MyClass&lt;int&gt;;
  template class MyClass&lt;float&gt;;
  </code></pre>
