Python is a common choice for "first programming language." Whats the problem with making it more friendly/helpful to beginners? I'm more worried that this PEP will make things more confusing for beginners. I see this PEP as a removal of some training wheels. It opens the door for much weirder behavior than warnings/error messages. Whenever I've reached for this feature, it's been to do something "clever" that I probably shouldn't have been doing in the first place. Sure, some people will do wonderful/helpful things with this feature. But lunatics like me will use this to do some absolutely unhinged things. I hope this PEP gets accepted, but I understand if the maintainers decide it's a bridge too far.
