Not specifically, except that, as I stated in another comment, an 
enumeration-case operation that checks exhaustiveness at expand-time would be 
natural and convenient to have.

So are enumeration sets, if I understand enum-set-indexer correctly.  But I had 
forgotten that record field names can be repeated, which would disqualify 
enum-sets for them.
