-// Parameter traits for movable-but-not-copyable scopers.
-//
-// Callback<>/Bind() understands movable-but-not-copyable semantics where
-// the type cannot be copied but can still have its state destructively
-// transferred (aka. moved) to another instance of the same type by calling a
-// helper function.  When used with Bind(), this signifies transferal of the
-// object's state to the target function.
-//
-// For these types, the ForwardType must not be a const reference, or a
-// reference.  A const reference is inappropriate, and would break const
-// correctness, because we are implementing a destructive move.  A non-const
-// reference cannot be used with temporaries which means the result of a
-// function or a cast would not be usable with Callback<> or Bind().
-//
-// TODO(ajwong): We might be able to use SFINAE to search for the existence of
-// a Pass() function in the type and avoid the whitelist in CallbackParamTraits
-// and CallbackForward.

-// CallbackForward() is a very limited simulation of C++11's std::forward()

-// argument to another function requires us to invoke the proper move
-// operator to create a rvalue version of the type.  The supported types are
-// whitelisted below as overloads of the CallbackForward() function. The
-// default template compiles out to be a no-op.
-//
-// In C++11, std::forward would replace all uses of this function.  However, it
