Description
Returns a randomly chosen element of the list, which may be different each time the function is run. nth-random respects nesting, i.e. if the list is a tree, the randomly chosen element may be an entire sublist of the tree. For example, if the list (1 (2 3) 4) is given, either 1 or (2 3) or 4 may result, but never 2 or 3 alone, since they occur within an element.
