-//
-// Example usage (scoped_ptr<T>):

-//   }  // foo goes out of scope, releasing the pointer with it.
-//

-//     foo.reset(new Foo("wee3"));   // Foo("wee2") was destroyed.
-//     foo->Method();                // Foo::Method() called.
-//     foo.get()->Method();          // Foo::Method() called.
-//     SomeFunc(foo.release());      // SomeFunc takes ownership, foo no longer
-//                                   // manages a pointer.
-//     foo.reset(new Foo("wee4"));   // foo manages a pointer again.
-//     foo.reset();                  // Foo("wee4") destroyed, foo no longer
-//                                   // manages a pointer.
-//   }  // foo wasn't managing a pointer, so nothing was destroyed.
-//
-// Example usage (scoped_ptr<T[]>):
-//   {
-//     scoped_ptr<Foo[]> foo(new Foo[100]);
-//     foo.get()->Method();  // Foo::Method on the 0th element.
-//     foo[10].Method();     // Foo::Method on the 10th element.
-//   }
-//
-// Scopers are testable as booleans:
-//   {
-//     scoped_ptr<Foo> foo;
-//     if (!foo)
-//       foo.reset(new Foo());
-//     if (foo)
-//       LOG(INFO) << "This code is reached."
-//   }
-//
-// These scopers also implement part of the functionality of C++11 unique_ptr
-// in that they are "movable but not copyable."  You can use the scopers in
-// the parameter and return types of functions to signify ownership transfer
-// in to and out of a function.  When calling a function that has a scoper
-// as the argument type, it must be called with an rvalue of a scoper, which
-// can be created by using std::move(), or the result of another function that
-// generates a temporary; passing by copy will NOT work.  Here is an example
-// using scoped_ptr:
-//
-//   void TakesOwnership(scoped_ptr<Foo> arg) {
-//     // Do something with arg.
-//   }
-//   scoped_ptr<Foo> CreateFoo() {
-//     // No need for calling std::move() for returning a move-only value, or
-//     // when you already have an rvalue as we do here.
-//     return scoped_ptr<Foo>(new Foo("new"));
-//   }
-//   scoped_ptr<Foo> PassThru(scoped_ptr<Foo> arg) {
-//     return arg;
-//   }
-//
-//   {
-//     scoped_ptr<Foo> ptr(new Foo("yay"));  // ptr manages Foo("yay").
-//     TakesOwnership(std::move(ptr));       // ptr no longer owns Foo("yay").
-//     scoped_ptr<Foo> ptr2 = CreateFoo();   // ptr2 owns the return Foo.
-//     scoped_ptr<Foo> ptr3 =                // ptr3 now owns what was in ptr2.
-//         PassThru(std::move(ptr2));        // ptr2 is correspondingly nullptr.
-//   }
-//
-// Notice that if you do not call std::move() when returning from PassThru(), or
-// when invoking TakesOwnership(), the code will not compile because scopers
-// are not copyable; they only implement move semantics which require calling
-// the std::move() function to signify a destructive transfer of state.
-// CreateFoo() is different though because we are constructing a temporary on
-// the return line and thus can avoid needing to call std::move().
-//
-// The conversion move-constructor properly handles upcast in initialization,
-// i.e. you can use a scoped_ptr<Child> to initialize a scoped_ptr<Parent>:
-//
-//   scoped_ptr<Foo> foo(new Foo());
-//   scoped_ptr<FooParent> parent(std::move(foo));
