Recently, I reported how stdlib slows down import requests. https://github.com/requests/requests/issues/4315#issuecomment-385584974 For Python 3.8, my ideas for faster startup time are: * Add lazy compiling API or flag in re module. The pattern is compiled when first used.

How about go the other way and allow compiling at Python compile-time? That would actually make things faster instead of just moving the time spent around.

I do see value in being less eager in Python but I think the real wins are hiding behind ahead-of-time compilation.
