Instead of special syntax, what if dict.values() returned a tuple when given keys as arguments:
partner_id, product_id, ship_to, product_ids = my_dict.values( 'partner_id', 'product_id', 'ship_to', 'product_ids')
I like this idea. I think it beats the status quo:
Isn't this the status quo? a, b, c = [mapping[k] for k in ('a', 'b', 'c')]
Yes.
Uhm, what about... from operator import itemgetter a, b, c = itemgetter('a', 'b', 'c')(mapping) (itemgetter is not the best name, but it does get the job done)
That was already someone's argument that a special dict unpacking syntax is unnecessary.
It looks really cool at first blush, but when substituting real names in for the place-holders a, b, and c it gets ugly fast.
