The PartialEq trait was added to maintain consistency because:

1. The Range struct already implements PartialEq, allowing for equality comparisons
2. RangeIterator is closely related to Range and should support similar operations
3. This enables users to compare RangeIterator instances when needed, just like they can with Range
