Filter + Multiselect and array key access

[mvhirsch]

I'm using this in one of my projects, testing my JSON API. I really like it, thank you for providing such a cool library!

I'm trying to filter my array, asserting that a specific value is returned in first match.
According to website this works:

people[?age >= `30`].{name: name}[0].name

{
  "people": [
    {
      "age": 20,
      "other": "foo",
      "name": "Bob"
    },
    {
      "age": 25,
      "other": "bar",
      "name": "Fred"
    },
    {
      "age": 30,
      "other": "baz",
      "name": "George"
    }
  ]
}

I'm not sure if I correctly understood the test setup on this (feel free to correct me!), but it may help understanding my issue :-)
