Not problematic. Just a little cumbersome. (And ugly, agreed.) You can't always just copy and paste some text into code, without adding escape encodings. Now write code that generates C code with strings, that generates C code with strings, and ... (ahem!) It's not a big deal, but it isn't zero friction either. Relevant here because it might be the most prevalent example of what happens when even two simple grammars collide.
