i’ve been meaning to write a Real Post™ on this but

amazing

all my personal stuff has been 3 as of late and it is so great

real text by default, neat builtins like enum and ipaddress and asyncio, a lot of old error-prone syntax gone, keyword-only arguments, etc

it’s a lot of relatively small stuff (so learning/porting aren’t really that bad) but in aggregate it’s pretty noticeable
