Obsolete Language Elements
The language elements described in this subnode are obsolete and are still available only for reasons of compatibility with older releases. These statements may still be encountered in older programs but should not be used in new programs.
Most of the obsolete language elements listed here are forbidden in the syntax of classes. This means they can now only be used outside of classes. There are replacement constructions for all obsolete language elements, which improve the efficiency and readability of programs.
