gh-104469 : Convert _testcapi/dict.c to use AC by jamie2779 · Pull Request #107859 · python/cpython

It significantly reduces readability to me.

It significantly increases the number of lines in Modules/_testcapi/dict.c:

 Modules/_testcapi/dict.c | 412 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++----------------------------------------------

And this is not counting the large amount of code added to another file.

I have a limited field of vision and can't see anything beyond a limited number of lines of code. Before that, test functions were compact. After these changes, they will exceed my limit. And if I need to understand what exactly the function does, I have to look for the corresponding code in the generated file and then go back to the previous file, but when I look from the file I lose the context and I have to reread each line on the screen again to find the right place.

These changes are not friendly to the visually impaired.
