[citation needed]

fair enough, but I think we all agree that many, if not most, Python users are "not professional programmers". While on the other hand everyone involved in discussion on python-dev and python-ideas is a serious (If not "professional") programmer.

So we do have a bit of a disconnect between much of the user base and folks making decisions about how the language evolves -- which is probably inevitable,

Over the years I've been using it (most of its life), Python has evolved to become much less of a "scripting" language, and much more of a "systems" language, and this addition is a (pretty significant) step more in that direction.

Serhiy: FWIW, a number of us made the case about the additional complexity of this feature in this discussion -- I think it was a bit side-tracked by the impression that we were only talking about newbies (and also by scope of comprehensions), but the point was made and I assume considered.

I'd call it "local namespace manipulating and non-local namespace manipulating", but yes, that is my concern as well.

In terms of blending mutating and non-mutating operations, augmented

assignment is far worse.

yeah -- I've always thought it was a shame that augmented assignment worked on immutables :-(
