decorated function.
The default implementation just returns *self*.
Overriding this method allows otherwise one-shot context managers
like _GeneratorContextManager to support use as decorators via
implicit recreation.

Allows an otherwise one-shot context manager like
_GeneratorContextManager to support use as

This is a private interface just for _GeneratorContextManager.
