What was their response to this? I think it's perfectly valid to state this, and may even throw the balance of the interviewer/interviewee dynamics but I can also see other people seeing this as obtuse. But pointing out a missing bracket (in a nonconstructive manner) on a whiteboard is pretty obtuse too...

It was the last interview of the day, and I was tired and had already decided I was almost certainly going to decline any offer, if given. So, honestly, I probably said it with a little bit of an edge and that was inappropriate on me.

Nevertheless, the interviewer was gracious and replied, "Fair enough" and stopped nitpicking my brackets and semicolons.

I got asked to find the intersection of two squares for a Django cosing job. I pointed out that it had absolutely nothing to do with Django (after getting a solution).

I was told they thought I might be difficult to work with.

Nice! Worth doing these things even if to personally experience the boundaries of good/bad interview practice.
