The era of pedantry is finally over:

Direct support for REPL-specific commands like help, exit, and quit, without the need to call them as functions.

FINALLY! This has always annoyed me. If you’re gonna go through all the trouble of identifying that I want to exit, just DO it.

It’s not really much extra effort though

They just added so e text to the __repr__ method on the exit callable object

That’s much easier than figuring out if your running this interactively and trying to figure out if this is going to break stuff.

Lemme golf that

~ $ python
Python 3.12.10 (main, Apr  9 2025, 18:13:11) [Clang 18.0.3 (https://android.googlesource.com/toolchain/llvm-project d8003a456 on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> class x:
...  def __repr__(s):
...   exit(0)
...
>>> xit = x()
>>> xit
~ $

Not that hard

repr is generally assumed to be side effect free and cheap to run, so things like debuggers tend to show repr of things in scope, including possibly exit

also then it behaves differently between repl and script, since repr never gets run. to do it properly it has to be a new repl keyword I imagine, but I still don't know if I'm sold on the idea

Good points. You're right, it does need solved at the shell level. Glad they did so.
