 OK, how can we express more clearly without explicit comments what our code does, i.e. make it self explaining?
 
 ```c++
-vector<int> squareVec6(const vector<int>& v)
+vector<int> squareVec5(vector<int> v)
 {
-    vector<int> result;
-    result.reserve(v.size());
-    transform(begin(v), end(v), back_inserter(result), [](int i)
+    transform(begin(v), end(v), begin(v), [](int i)
     {
         return i*i;
     });
-    return result;
+    return v;
 }
 ```
 `std::transform` tells the reader at one glance that all `v.size()` elements of `v` will be transformed into something else.
