note that most examples of this type already work, if the target type is mutable, and implement the right operations:

def counter(num): num = mutableint(num) def inc(): num += 1 return num return inc I agree with you (and argued it in "scopes vs augmented assignment vs sets" recently) that mutating would be sufficient /if/ the compiler would view augmented assignment as mutations operators

feel free to replace that += with an .add(1) method call; the point wasn't the behaviour of augmented assigment, the point was that that the most common use pattern involves mutation of the target object.

the syntax isn't that important, really.
