Array items with multiply keys are not loaded properly

[atorkhov]

---
list:
  - elem1:
      elem1_1: data1
    elem2: data2

list will become Array object with additional elem2 property. I don't know how properly format it in JSON, but something like this:

{
  list: {
    0: { elem1: {elem1_1: "data1" } },
    elem2: "data2"
  }
}

I was expecting:

{
  list: [
    { elem1: { elem1_1: "data1" },
      elem2: "data2" }
  ]
}
