If a list has 5 elements the indices go from 1 to 5, so a range of ``2..16`` will only go from element 2 to element 5. If a list has 5 elements the indices go from 1 to 5, so a range of ``2..16`` will only go from element 2 to element 5.
If the end is negative the range always goes up, so ``2..-2`` will go from element 2 to 4, and ``2..-16`` won't go anywhere because there is no way to go from the second element to one that doesn't exist, while going up. If the end is negative the range always goes up, so ``2..-2`` will go from element 2 to 4, and ``2..-16`` won't go anywhere because there is no way to go from the second element to one that doesn't exist, while going up.
If the start is negative the range always goes down, so ``-2..1`` will go from element 4 to 1, and ``-16..2`` won't go anywhere because there is no way to go from the second element to one that doesn't exist, while going down. If the start is negative the range always goes down, so ``-2..1`` will go from element 4 to 1, and ``-16..2`` won't go anywhere because there is no way to go from an element that doesn't exist to the second element, while going down.
A missing starting index in a range defaults to 1. This is allowed if the range is the first index expression of the sequence. Similarly, a missing ending index, defaulting to -1 is allowed for the last index range in the sequence. A missing starting index in a range defaults to 1.
