Importing typing on this macOS M2 (python3.14 -X importtime -c 'import typing') is also slower with Python 3.14 (taking 5 ms) due to it importing the new annotationlib (itself taking 4 ms, mostly due to importing ast), compared to 3ms for typing on 3.13 (python3.13 -X importtime -c 'import typing').
And with hyperfine:
python3.13 -c "import typing" ran
1.16 ± 0.46 times faster than python3.14 -c "import typing"
Compared to:
python3.14 -c "pass" ran
1.15 ± 0.07 times faster than python3.13 -c "pass"
