I'd consider it in a similar class as the dictionary lookup that occurs when an unknown symbol is encountered. Totally unnecessary, but it's a nice time-saver. Is it clang that displays the line in error with a carat underneath the error? Though if there really isn't an efficient way to do it in DMD then I don't think it's worthwhile. I was only thinking of the parser when I mentioned the beginning-of-line pointer. I hadn't considered the AST.
