I look forward to reading this article when I have the time because I am a Go newbie, so a well explained example program will be useful to me. Also, I find language implementation interesting, and I've always admired the AWK language. I for one and glad he did it and wrote an article explaining it.

Finally, I think it is good to see C software being rewritten in more robust languages like Go and Rust, if people are inclined to do so. I don't think rewriting all the C software should be our top priority, especially high-quality programs like AWK, but it's a good overall direction to go when people are interested.
