12c - plsql function in with clause

Question

Hi all
I'm mucking around with 12c:
SQL> select *
  2    from v$version;
BANNER                                                                               CON_ID
Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit Production              0
PL/SQL Release 12.1.0.1.0 - Production                                                    0
CORE    12.1.0.1.0      Production                                                                0
TNS for Linux: Version 12.1.0.1.0 - Production                                            0
NLSRTL Version 12.1.0.1.0 - Production                                                    0
5 rows selected.
specifically I'm trying to use the new functionality of putting a pl/sql function in the WITH clause of an SQL statement:
docco here:
http://docs.oracle.com/cd/E16655_01/server.121/e17209/statements_10002.htm#BABJFIDC
the example they give is:
WITH
FUNCTION get_domain(url VARCHAR2) RETURN VARCHAR2 IS
  pos BINARY_INTEGER;
  len BINARY_INTEGER;
BEGIN
  pos := INSTR(url, 'www.');
  len := INSTR(SUBSTR(url, pos + 4), '.') - 1;
  RETURN SUBSTR(url, pos + 4, len);
END;
SELECT DISTINCT get_domain(catalog_url)
  FROM product_information;
and so I produced my own hello world version:
with function add_number(num1 number, num2 number) return number is
begin
   return num1 + num2;
end;
select add_number(1,2) from dual;
but this just doesn't compile in SQL developer or SQLPlus.   do I need to get an updated version or something perhaps?
output is:
SQL> with function add_number(num1 number, num2 number) return number is
  2  begin
  3     return num1 + num2;
with function add_number(num1 number, num2 number) return number is
ERROR at line 1:

Hi,
does that mean that you still have the problem, even after fixing this? Because I don't:
