[babel_]

I think they mean {a: x, b: y, *c} = d, which is a nice idea now we have a stable order to dicts, but I've rarely come across times when I needed this that I can't simply use .items() and such for, or care about more general pattern matching like values for specific keys, which you can just do a, b = d["a"], d["b"] with little loss of clarity, sure {"a": a, "b": b} = d is cute and all, and maybe we'll oneday see it now we have match as syntactic precedent, but I don't really feel concerned by its absence.
