I was sitting today, thinking how unfortunate it is that C/C++ don't have any string quoting operators other than double-quote. I mean, designers of all sorts of languages since then (perl, in the especially extreme case) have figured out that if you want to print double quotes, that's just no fun at all.
Then I realized I was wrong.
#define qq(s) #sint main() { printf(qq(blah blah\n "quoted" stuff (and some parens) with newlines)); return 0; }
Try it. It works.
