 Given 3 String parameters `input`, `pattern`, `replace`, this function will replace any occurrence matching `pattern` in `input` by `replace`.
 `pattern` is expected to be a [regular expression](https://en.wikipedia.org/wiki/Regular_expression). Details of regex evaluation will depend on the execution engine running the WDL.
 
+## Array[Int] range(Int)
+
+Creates an array of integers of length equal to the range argument. For example `range(3)` provides the array: `(0, 1, 2)`.

+## Array[Array[X]] transpose(Array[Array[X]])
+
+Transposes a two dimensional array according to the standard matrix transpose rules. For example `transpose( ((0, 1, 2), (3, 4, 5)) )` will return the rotated two-dimensional array: `((0, 3), (1, 4), (2, 5))`.
