If you can easily convert it to a tail-recursive function, then you 
don't need to record any stack info, and its as easy as recording the 
current arguments like Jon Harrop pointed out.

Converting a recursive function to a tail-recursive one is as hard as 
converting it to an interative algorithm: the two forms are pretty much 
the same.
