(Heretical question: do we *really* need to distinguish it in syntax? Iterator unpacking a dict seems like a dumb idea, I wouldn't be sad if we broke compatibility there)
Breaking millions of lines of idiomatic code seems like a bad idea.
a, b, c = mydict
Mary not be so very common, but this is ubiquitous:
for k in mydict: ...
What I mean is that maybe `a, b = foo` could first test if `foo` is a mapping, use mapping unpacking if it is, otherwise fall back to regular iterable unpacking. So dicts would remain iterable, but that wouldn't feature in unpacking. Then there wouldn't be a change in syntax, or in other kinds of iteration, just a change in what happens if you unpack a dict.
