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.
