conditional DDL statements

Hi, I am afraid I know the answer to this already ("not supported"), but I wanted to check with you guys. Perhaps someone has smart workaround? Essentially what I would like to do is something like: IF condition THEN CREATE FUNCTION ....; As far as I know, flow control statements are only allowed inside functions/procedures. However, CREATE statements are not allowed inside functions/procedure. So I don't see any way to do what I wrote above. Notice, I am aware of CREATE OR REPLACE. What I'm looking for is an arbitrary condition test. Any trick? And/or, any plan to implement something in this direction? Roberto
