VTK and ITK are using auto in a lot of cases.<br /> <br /> <br /> <br /> '''Move not implemented constructors and assignment operators to the public interface''' <br /> <br /> Now that we use = delete, we don't need the constructors and assignment operator to be in the private interface.<br /> Moving them to the public interface is better.
