I missed these on the first pass because in the legacy function table they are, for some reason, added in a different place than the others.

element Function
element retrieves a single element from a list.
element(list, index)
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.
Examples
> 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
