What methods and properties do Vala arrays support?

Question

The Vala Tutorial mentions the following methods and properties (and operators) for built-in arrays:

arr.length
arr += element
arr.resize()
arr.move()

(By "built-in arrays" I mean ones like int[] arr = new int[5], in contrast to the fancy data structures provided by GLib or Gee.)

My question: do such arrays support any more methods and properties? Where is this documented?

Answer 1

According to the compiler source code there should also be arr.copy():

Also if you look at the unit tests you can see that slices (e.g. arr[1:5]) are a feature of arrays:

But I think thats it. The built-in array is pretty minimalistic.
