+// Scopers help you manage ownership of a pointer, helping you easily manage a
+// pointer within a scope, and automatically destroying the pointer at the end
+// of a scope. There are two main classes you will use, which correspond to the
+// operators new/delete and new[]/delete[].
+//
+// Example usage (scoped_ptr<T>):
+// {
+// scoped_ptr<Foo> foo(new Foo("wee"));
+// } // foo goes out of scope, releasing the pointer with it.
+//
+// {
+// scoped_ptr<Foo> foo; // No pointer managed.
+// foo.reset(new Foo("wee")); // Now a pointer is managed.
+// foo.reset(new Foo("wee2")); // Foo("wee") was destroyed.
+// 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.
+// }
+//
+// 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 the result of an analogous
+// scoper's Pass() function or 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 Pass() because we are constructing a temporary
+// // for the return value.
+// return scoped_ptr<Foo>(new Foo("new"));
+// }
+// scoped_ptr<Foo> PassThru(scoped_ptr<Foo> arg) {
+// return arg.Pass();
+// }
+//
+// {
+// scoped_ptr<Foo> ptr(new Foo("yay")); // ptr manages Foo("yay").
+// TakesOwnership(ptr.Pass()); // 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(ptr2.Pass()); // ptr2 is correspondingly NULL.
+// }
+//
+// Notice that if you do not call Pass() 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 Pass() 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 Pass().
+//
+// Pass() 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(foo.Pass());
+//
+// PassAs<>() should be used to upcast return value in return statement:
+//
+// scoped_ptr<Foo> CreateFoo() {
+// scoped_ptr<FooChild> result(new FooChild());
+// return result.PassAs<Foo>();
+// }
+//
+// Note that PassAs<>() is implemented only for scoped_ptr<T>, but not for
+// scoped_ptr<T[]>. This is because casting array pointers may not be safe.
