I still don't understand the "feature creep" complaint

python just introduced built-in sentinel, and only comment on an explainer video brought up that it's nothing new and is just a rename of unittest.mock.sentinel

who even knew there's unittest module? who even knew there's unittest.mock? definitely not me

because it doesn't matter - you use what you need and learn what you encounter. Same thing with C++

There's a big difference between a function or class that you didn't know about (or has just been added to the standard library) vs a new language feature.

Python isn't immune from those either by the way (e.g. walrus operator, pattern matching) but nowhere near C++ level.

also "do you still enjoy X" is a loaded question

do you still enjoy speaking english?
