Sorry no time to look thru details BUT when you have mut rec specs of  
data, you get mut rec functions to process them. And yes, in that  
case it's nearly impossible to write independent tests (and find

BTW, I didn't see any check-expects and test-examples but this could  
be due to your formatting. You might be better off posting a url to a  
solution. My Mail client scrambles your posting.
