Ranges can also be used to extract slices of arrays.
With two dots (<tt>3..6</tt>), the range is inclusive (<tt>3, 4, 5, 6</tt>);
with three dots (<tt>3...6</tt>), the range excludes the end (<tt>3, 4, 5</tt>).
Slices indices have useful defaults. An omitted first index defaults to
zero and an omitted second index defaults to the size of the array.
