I looked at this six years ago. I still haven't found a situation where I pined for a NamedTupleReader. That said, I have no objection to committing it if others, more well-versed in current Python code and NamedTuples than I gives it a pass. Note that I added a couple comments to the csv.py diff, but nobody either updated the code or explained why I was out in the weeds in my comments.
