    What if I want to put a backslash character in my string?  e.g. I want to produce 'some \ string'.
    
    I don't think this worked before, but it's particularly relevant because now we're doing stuff with backslash.  In particular, I don't think this worked before because (and correct me if I'm wrong)
    
    ```
    fragment SCHAR:  ~['"\\\r\n];
    ```
    This says that strings are NOT:
    * Single Quote
    * Double Quote
    * Backslash
    * Carriage Return
    * Newline
    
    Even escaping won't help this, because the backslash is outright disallowed in strings.  Is there a reason it's not allowe?
