            oops, tiny typo in those code examples, they should say `group=` instead of `name=` -- though the performance is unchanged: (first example) ```console $ ./venv39/bin/python t.py 0.6641988754272461 $ ./venv310/bin/python t.py 1.3172023296356201 ``` (second example) ```console $ ./venv39/bin/python t.py 0.014233589172363281 $ ./venv310/bin/python t.py 8.910593271255493 ```  |      |
