Inlined array elements with JBuilder

How do you create an array with elements in it using Jbuilder without setting it to a variable first?

I want to end up with the following while using JBuilder

{
  "something": [
    { "name": "first", "foo": "bar"},
    { "name": "second", "foo": "baz"}
  ]
}

The only method I have found that works is the following.

json.something do
  something = [
    { name: 'first', foo: 'bar' },
    { name: 'second', foo: 'baz' }
  ]
  json.array! something do |item|
    json.(item, :name, :foo)
  end
end

Is there a way to make it look more like this?

json.array! 'something' do
  json.array do
    json.name 'first'
    json.foo 'bar'
  end
  json.array do
    json.name 'second'
    json.foo 'baz'
  end
end

The only thing similar that I can imagine is use hardcoded hash:

json.something do
   json.array! [
     {name:'first',foo:'bar'},
     {name:'second',foo:'baz'}
   ]
end
