This is as easy as providing a java.lang.Iterable as part of the configuration:

let result = array[1, 2, 3]
let conf = map[
  ["interfaces", ["java.io.Serializable", "java.lang.Runnable"]],
  ["implements", map[
    ["run", |this| {
      for (var i = 0, i < result: length(), i = i + 1) {
        result: set(i, result: get(i) + 10)
      }
    }]
  ]]
]
let runner = AdapterFabric(): maker(conf): newInstance()
runner: run() # (1)
