2. I hadn't really thought of the PEP in those terms. Now that you've mentioned it, "Python has never before had syntax that assigns names from within an expression" is quite a significant change, and one the PEP needs to examine the implications of. It's mostly been covered in the discussions by now, of course.

Depending on your definition of "assignment", a lambda function could count as a means of assigning a variable in a subexpression. But yes, there is no convenient way to assign to something in a wider scope.
