title: std::inserter not working
body: <p>I am writing a code, in which one of the files uses set_intersection function, and the last parameter to this function is supposed to be an inserter. But when I compile the code, I see the following errors:</p>
  
  <pre><code>error C2039: 'inserter' : is not a member of 'std'
  error C2873: 'inserter' : symbol cannot be used in a using-declaration
  error C3861: 'inserter': identifier not found
  </code></pre>
  
  <p>Following is the code in the file which uses set_intersection function</p>
  
  <pre><code>#include "Query.h"
  #include "TextQuery.h"
  #include &lt;set&gt;
  #include &lt;algorithm&gt;
  #include &lt;iostream&gt;
  
  using std::set;
  using std::ostream;
  using std::inserter; 
  using std::set_intersection;
  
  // returns intersection of its operands' result sets
  set&lt;TextQuery::line_no&gt;
  AndQuery::eval(const TextQuery&amp; file) const
  {
      // virtual calls through the Query handle to get result sets for the operands
      set&lt;line_no&gt; left = lhs.eval(file), 
                   right = rhs.eval(file);
  
      set&lt;line_no&gt; ret_lines;  // destination to hold results 
  
      // writes intersection of two ranges to a destination iterator
      // destination iterator in this call adds elements to ret
      set_intersection(left.begin(), left.end(), 
                    right.begin(), right.end(),
                    inserter(ret_lines, ret_lines.begin()));
      return ret_lines;
  }
  </code></pre>
