PR Review

⏱️ Estimated effort to review [1-5]	2, because the PR involves a simple logic change in a setter method, which is straightforward to understand and verify. The change is localized to one condition in one method, making the review process relatively quick.
🧪 Relevant tests	No
🔍 Possible issues	Possible Bug: If self._point_columns is not initialized or is dynamically changed elsewhere in the code, the new condition could lead to unexpected behavior or errors. It's important to ensure that self._point_columns is always properly set before this setter is called.
🔒 Security concerns	No

Code feedback:

---

relevant file	discretisedfield/line.py
suggestion	Consider adding a null or type check for self._point_columns before comparing its length to val. This will prevent potential TypeError or AttributeError if _point_columns is None or not an iterable. [important]
relevant line	if len(val) != len(self._point_columns):
