Do you want reverse execution, like an undo function? Undo all changes  
made by executing some piece of code?
There are many cases where that's hard to do, or impossible. How to undo  
object destruction? How to undo external effects, like writing to files?
You should think carefully what can and cannot be done - good luck!
