No, I don't think anybody has a satisfactory approach to updating polymorphic/higher-ranked fields. (DORF mentions one, but it's a ghastly hack.
So are the proposals dead until this is tackled, or should SORF/DORF propose not to allow that?
That's an important question. I've asked in the DORF proposal how big is the demand to update h-r fields? Note that is something you can do currently with H98 records/fields. Is it good enough to be able to extract and use h-r fields in polymorphic contexts? (Both SORF and DORF can do that.) Is it good enough to be able to create records with h-r fields (using the data constructor)? (Both SORF and DORF can do that.) AntC
