Numeric keys + deep lists = trouble

[bitnom]

Please consider the following:

"2019": {
    "uat": {
      "pkey": true,
      "user": "testval",
      "testkey": true,
      "mylist": [
      {
        "foo": "bar",
        "foo2": "bar2"
      },
      {
        "baz": "milk",
        "bar": "foo"
      }
      ]
    },
    "dev": {
      "pkey": true,
      "testval": "testval",
      "testval2": true
    },
    "test1": [1, 2, "testval"],
    "test2": [{"one": "foo", "two": "bar", "three": "testval"}]
  }
}

There is no way to access deep lists now. If I use no_list=True I will be in trouble because 2019 will work as key but then I can't access mylist. This has me stuck in a project. I've been trying to make some function to parse the key tree and flip no_list on and off while traversing but it's not straight forward what to do.

Reason:

If I need to copy the data schema, I can't make new dotty() and then say:

new["2019.uat.mylist.0"] = dotty(data)

because numeric will always be a list or a key. No mix.

Solution Request:

Identifier for lists in leafy strings. Maybe like:

"2019.uat.mylist.[0]"
