Y'all, you should be so hyped up about Python 3.15, and specifically about lazy imports. I just merged a PR to move argparse to lazy imports for Python 3.16. On my machine, it reduces the median cumulative time for a bare `import argparse` by ~67%! github.com/python/cpyth...

GH-154638: Use lazy imports in argparse by savannahostrowski · Pull Request #154639 · python/cpythonIssue: Use lazy imports in argparse #154638github.com

The discussion thread on this has been relentless github.com/tonybaloney/...

It was to be expected, but I need to stress how much #EuroPython benefitted from being the host of the CPython Core Summit this year. As I keep repeating, the main value of #PyConUS for the COMMUNITY is the gathering of stakeholders for in-person exchange. 1/2
