A $ prefix would act at parse time, i.e., $"answer: $answer" would be 
equivalent to ("answer: " + str(answer)).  like r and u, $ would change 
the meaning of the literal, it wouldn't be an operator, and so this 
would be a syntax error:

     answer = 1
     msg = "answer: $answer"
     print $msg

Though I also agree that $"answer: $answer" introduces a confusing 
number of $'s.
