There seems to be a lot of resistance to dict unpacking, in addition to the problem with my proposed shorthand dict() initialization syntax pointed out by Steven D'Aprano, so I won't be pursuing this. > -- > https://mail.python.org/mailman/listinfo/python-list something like: a, b, c = my_magic_reordering_func(mydict, ["alpha", "beta", "charlie"]) ..is not too far off, altho it is a little repetitive is is trivial to write in current python and reaches the goal of insulating you from some degree of change in the return value. can also be extended to work with namedtuple for example (which you probably should already be using if you want to return so many arguments that this is a problem, returning several arguments is already returning a tuple under the hood afterall)
