I close the issue. Making more imports lazy doesn't bring much benefit.

With the 3 changes, runpy now imports 55 modules, instead of 70.
The startup time is 1.3x faster, 18 ms instead of 24 ms:
Mean +- std dev: [before] 23.7 ms +- 0.4 ms -> [after] 17.8 ms +- 0.6 ms: 1.33x faster (-25%)

Avoiding itertools and types doesn't bring much benefit:
Mean +- std dev: [after] 17.8 ms +- 0.6 ms -> [WIP] 17.2 ms +- 0.4 ms: 1.03x faster (-3%) |
