Argh! I did not thought about it. So it may means that my changes are breaking the system. Aliaksei DNU is a ship way. The other way is as you expect I'm sure adding a method that just does the delegation. What we can do is to turn the DNU into a DNU compiling methods like that after a while we will have the method compiled and we will able to remove the DNU trick.
