title: Template Partial Specialization - any real-world example?
body: <p>I am pondering about <code>partial specialization</code>. While I understand the idea, I haven't seen any real-world usage of this technique. <code>Full specialization</code> is used in many places in <code>STL</code> so I don't have a problem with that. Could you educate me about a real-world example where <code>partial specialization</code> is used? If the example is in <code>STL</code> that would be superior!</p>
