I would never insult someones writing or speaking ability in a non native language - as long as the meaning is conveyed then it's a success as far as i'm concerned, and especially in this case given that Stefan's English is far superior to what my German will ever be.
That said, I do find it ironic that he is adamant on becoming an expert before doing something, considering he wrote a book in English without having high level comprehension. Every other sentence is structurally incorrect and littered with errors. I know in German the order of certain words can be changed and its fine, but that's not the case in English. Nim In Action on the other hand is extremely well written, and given the stage of Nim as an emerging language, I think it targets exactly the right level. A Nim book today should assume general knowledge in programming. The book hits the sweet spot of catering to relative beginners quite succinctly while also covering more high level topics. You will struggle to find a better book for any other language and I think Dom and Nim should be proud of it. There is plenty of excellent content already in existence to teach programming fundamentals, its not a high priority of Nim to add to that at this point. Maybe in the distant future Nim could be used to teach programming, although I would argue that C should always be the first step of anyone who is serious about it.
