I think the solution to that is straightforward: tell users that we hope 
to eventually support loops and that in the meantime if you try to work 
around that with recursion you get to keep both pieces when it breaks. 
While not ideal I think that's a lot better than throwing the whole idea 
out because some people will abuse it...
