And, with a dataclass added...

@dataclasses.dataclass()
class A:
    a: int
    b: "list[int]"

items = (
    {("a", 1): 3.4, 2: {5, 6}},
    {3: A(5, [12, 3])},
)
for (item, path) in walker(items):
    with visitor(item, path=path):
        pass


...that's what we get:

     [0] => {('a', 1): 3.4, 2: {5, 6}}
         [0][('a', 1)] => 3.4
         [0][2] => {5, 6}
             [0][2][5] => 5
             [0][2][6] => 6
     [1] => {3: A(a=5, b=[12, 3])}
         [1][3] => A(a=5, b=[12, 3])
             [1][3]['a'] => 5
             [1][3]['b'] => [12, 3]
                 [1][3]['b'][0] => 12
                 [1][3]['b'][1] => 3


That said, I still think that we must somehow designate that in case of
dataclass we access not by index but by an attribute. With that in mind,
perhaps the path should be somewhat more flexible than it is, and have
different types: AttributePath, DictItemPath, SetPath and IndexPath. This way
the repr can be handled.
