+Using splat arguments can simplify inserting list in list:

+    val x = [1, 2, 3]
+    x.addAt( 1, ...[0,100,0])
+    x
+    >>> [1, 0, 100, 0, 2, 3]

+Using negative indexes can insert elements as offset from the end, for example:

+    val x = [1,2,3]
+    x.addAt(-1, 10)
+    x
+    >>> [1, 2, 10, 3]

+Note that to add to the end you still need to use `add` or positive index of the after-last element:

+    x.addAt(3, 10)
