Why force unpacking? Why not assign a tuple? That would look like a simple assignment: x := (alpha, beta, gamma) And you could access x[0], x[1] and x[2].
I think asking := to support x, y := alpha, beta is a request to address an unnecessary, easily worked around, issue. And as previously pointed out you can still just use = . --- Joseph S.

I can't think of any other reasons. But the one you cite is quite an important one. In order to get real-world usage examples, the feature was rolled out in the restricted form, because threads like this are *exactly* how the value can be judged. So I do not in any way regret that assignment expressions were accepted in their current form, but also, don't be afraid to propose an opening up of the syntax. Be specific, and cite usage examples that would benefit. TBH, I don't think there's a lot of value in multiple-assignment, since it has a number of annoying conflicts of syntax and few viable use-cases. But if you have great examples of "x.y :=" or "x[y] :=", then by all means, post on python-ideas to propose widening the scope. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
