Comments
It's actually enough to provide a single list to Zip(). This makes it a shorter alternative to Sequence() when all you want is to traverse a list. For example, Zip(a^2, a, listOfNumbers) is much shorter than Sequence(Element(listOfNumbers, a)^2, a, 1, Length(listOfNumbers)) (albeit in this case it's easier to just do listOfNumbers^2.)
Hint: Zip() is similar to a construct known as "map" in other programming languages.
