The whole point of the piece seems completely lost on some readers. Yes, we all know that #define $(a,b) if(a)b;else is questionable. I don't need a crash course on C macros in the comments, thank you. The author already acknowledges that Whitney's style is controversial. Do we really need to keep rehashing that point in every comment, or can we finally focus on how all this unconventional code fits together beautifully to form a working interpreter?
