...destructor function to free the memory when the reference count goes to zero. The special implementation of slicing for the bytes object allows multiple bytes objects to refer to the same pointer/destructor. As such, a refcount will be kept on the actual pointer/destructor. This refcount is separate from the refcount typically associated with Python objects. XXX: It may be desirable to expose the inner refcounted object as an actual Python object. If a good use case arises, it should be possib...

...destructor's execution is not guaranteed in the first place. This seems to be a reasonable compromise, the resulting global behavior being similar to that of files and closing. Possible Semantics The built-in generator type should have a close method implemented, which can then be invoked as: gen.close() where gen is an instance of the built-in generator type. Generator destruction should also invoke close method behavior. If a generator is already terminated, close should be a no-op. Otherw...
...definitions are applicable. New Coroutine Declaration Syntax The following new syntax is used to declare a native coroutine: async def read_data(db): pass Key properties of coroutines: async def functions are always coroutines, even if they do not contain await expressions. It is a SyntaxError to have yield or yield from expressions in an async function. Internally, two new code object flags were introduced: CO_COROUTINE is used to mark native coroutines (defined with new syntax). CO_ITE...
