I think item 2 from Franscisco's thread is looking for an easy way to add
and remove fields from a record, producing a new record with a different
type. Let me just abuse the list append (++) operator to give the idea of
how a field would be added:
someRecord ++ { newField = "blah" }
The long hand version might be
addNewField someRecord =
{ newField = "blah", someRecord.existingField1,
someRecord.existingField2, ... }
Not sure how I feel about operations that produce records of a different
type, but if its really just syntax sugar for something you can write out
in long hand, it does not seem so unreasonable.
