	Iterable	Iterator
Protocol's required methods	__iter__(self) -> Iterator[T]: returns an iterator	__next__(self) -> T: returns the next element or raises StopIteration __iter__(self) -> Iterator[T] : returns itself
abc interface's required methods	__iter__(self) -> Iterator[T] (same as protocol)	__next__(self) -> T (same as protocol) not __iter__(self) -> Iterator[T] because it's aleady there

• Implementing the Comparable protocol
• Checking for inconsistencies between implemented Comparable methods
• Rules for using <, >, etc.
