element retrieves a single element from a list.
The index is zero-based. This function produces an error if used with an empty list.
Use the built-in index syntax
list[index] in most cases. Use this function
only for the special additional "wrap-around" behavior described below.
> element(["a", "b", "c"], 1) b
If the given index is greater than the length of the list then the index is "wrapped around" by taking the index modulo the length of the list:
> element(["a", "b", "c"], 3) a
