You can already write

     String mySub = apply(myVeryLongNamedString,
         (s) -> s.substring(s.indexOf("C"), s.indexOf("Q")))

with a helper function like this:

     public static <T, R> R apply(T value, Function<T, R> func) {
	return func.apply(value);
     }


You don't even need to repeat the type.  But the explicit version isn't 
too bad, either:

     String mySub;
     {
         String s = myVeryLongNamedString;
         mySub = s.substring(s.indexOf("C"), s.indexOf("Q"));
     }

So I'm not sure if leading dot expressions are all that helpful.
