Here it's important that index lists with trailing zeros are treated just like this list without the zeroes, so we can handle any number of dimensions. We want the same flexibility when adding index lists:

To demonstrate the easy of introducing even more dimensions, let's implement commands ( and ) to move the data pointer along the z-axis, and a command ^ to rotate the IP direction around the (1,1,1) axis (i.e., left becomes up, up becomes "further" on the z-axis, "further" becomes left, etc.).
