v1.23 -> v1.24 Upgrader

[Hoernchen]

We all know that soon the new version 1.24 of WarCraft 3 will come out and totally screw every map that uses the return bug, so basically every decent map out there. Question is, would there be any way for someone to create a Program that somehow converts maps from v1.23 to v1.24, fixing and replacing the old return bug with the new functions from Blizzard?

I could make one, but I'm not good at JASS. Is there a code example for it, and what are the new functions from Blizzard?
