Access via ranges and slices now behave identically to Ruby arrays. The fixes are mostly for out of range indices and lengths. - Zero length slice requests return an empty container instead of nil. - Slices which request a length greater than the size of the container no longer chop off the last element. - Ranges which used to return nil now return an empty array when the the start element is a valid index.
