Ulf,
I think that point leading style is something which can be easily mistreat. If 
we complicate the example:

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

to something like:

    String mySub = 
myVeryLongNamedString.concat("BLAH").substring(.indexOf("C"),.indexOf("Q"));

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.
