One of the things in this section that is not touched on at all is how to create and work with multidimensional arrays.
I do a lot of mathematical code and I often need two and three dimensional arrays and I see no explanation of how to deal with those in kotlin
I think that would be a good addition to this section

Unfortunately we had to leave this information out for reasons of space. Chapter 6 is already one of the longest chapters in the book, and given that multi-dimensional arrays are just a straightforward combination of already documented features, rather than a new feature that needs to be described separately, we decided that it would be best not to describe them.

You can find examples for their use, among other places, on StackOverflow: http://stackoverflow.com/questions/27512636/two-dimensional-int-array-in-kotlin
