This thread shows the large gap that exists between _Youtube Certified Engineers_ and _Old School Engineers_... ;-)
@Stefan_Salewski, perhaps is it interesting in your book to present not only Nim syntax and philosophy, but also elements of algorithms and data structures. The foundational bricks of computer science. For instance basis of O(n) notation to select algorithms. Or explain why Nim has 3 distinct string types (`string`, `cstring` and `ropes`). What's behind the `table[]` data structure? What optimize mean... etc.
