I sent a PR and measured how it affected the performance by creating a
dataclass with 10000 members.
python.bat -m timeit -s "from dataclasses import make_dataclass" -s "arg_list =
[chr(k) * i for k in range(97, 123) for i in range(1, 500)]"
"make_dataclass('a', arg_list)"
The performance didn't change, both before and after the changes it takes
around 14.5s.
