What's the problem for this package????

Question

My Package is :
CREATE OR REPLACE PACKAGE MY_PAQ IS
TYPE RESULT IS REF CURSOR;
FUNCTION MY_FUN
RETURN RESULT;
END MY_PAQ;
CREATE OR REPLACE PACKAGE BODY MY_PAQ IS
FUNCTION MY_FUN
RETURN RESULT
IS
C RESULT;
BEGIN
OPEN C FOR SELECT * FROM MY_TAB;
RETURN C;
END MY_FUN;
END MY_PAQ;
SQL> SELECT MY_PAQ.MY_FUN FROM DUAL;
SELECT MY_PAQ.MY_FUN FROM DUAL
ERROR at line 1:
ORA-00902: invalid datatype
I like that my function returns a set of rows from a table(s)
thanks in advance
Mario

Mario,
Package seems okay. However since the function returns an open cursor, one suggested option is as follows:
sqlplus > variable test_cursor refcursor;
use this bind variable and call the function
sqlplus > exec :test_cursor := MY_PAQ.MY_FUN;
sqlplus > print test_cursor;
