   Hi @davidszotten,

   There's #10209 open to at least fall back to native traceback printing temporarily, #9159 tracks the full support.

   hi @nicoddemus , thanks for the quick reply. just to be clear, i'm talking about

   https://docs.python.org/3.11/whatsnew/3.11.html#enhanced-error-locations-in-tracebacks

   Traceback (most recent call last):
     File "distance.py", line 11, in <module>
       print(manhattan_distance(p1, p2))
             ^^^^^^^^^^^^^^^^^^^^^^^^^^
     File "distance.py", line 6, in manhattan_distance
       return abs(point_1.x - point_2.x) + abs(point_1.y - point_2.y)
                              ^^^^^^^^^
   AttributeError: 'NoneType' object has no attribute 'x'
   

   not exception groups. or are the two tied together?

   🤦 Sorry indeed they are not related, sorry for the confusion.

   I don't think we have any plans regarding that (a quick search did not turn out much), but this is something we should definitely look into.

   Btw you asked for pointers: the traceback printing code starts in ExceptionRepr.toterminal, it should be possible to figure out/understand the code from there.

   You can of course get the native representation with pytest --tb=native, but it would indeed be good to support the more precise locations in long, short, and auto modes too 🙂

    Made a draft pull request with a proof of concept implementation #13102

    There's a few issues that need to be ironed out that I pointed out in there if anyone feels like driving it to completion.
