Brett CannonLet's say CPython can gain a JIT or get rid of the GIL, but not both. Which would you want to have more?
JIT
No GIL

@brettcannon ho ho! controversy. Have people also put "how many years have you been using Python?" and watch the old timers all go for JIT
@brettcannon a JIT would make life immediately better. no GIL would be...how would that even work, would modules have to declare "from __future__ import nogil" to guarantee that they have used threading.Lock() every time they pop from a dictionary? common people VOTE FOR JIT
Jonathan LaCour@zzzeek @brettcannon strong agree, coming from the view that the GIL was a good idea in the first place. It was a tradeoff that acknowledged that most software isn’t massively parallel. Even with decades of progress, single-threaded performance continues to be king. A truly great JIT would be transformative. Getting rid of the GIL would be great, but would require significant code and architectural changes to take advantage. Gimme dat JIT!
@jonathan @brettcannon WEIGHT THE POLL FOR VETERANS
@zzzeek @brettcannon raise your hand if your ~/.vimrc is older than most of the voters! :D
