I  would not be happy with  this solution - it creates yet more,  
seemingly unecessary terms, and it also was, in DAML days, the single  
feature name that confused the most people - I thought we were  
proposing a clean solution that didn't require creating a new  
syntactic feature, this is quite different - so I oppose closing this  
issue with Peter's suggested solution.
