Quoting Yitzchak Gale <[email protected]>:
Yes. The translation of record updates given in the Report
makes perfect sense for {}. It is only forbidden by
"n >= 1", but no reason is given for that restriction.
It doesn't make sense to me. The translation explodes a value into a
case statement over its constructors; what constructors do you use
when you don't know the type of the value?
When n >= 1, you know the type of the value by looking where the field
came from, and hence which constructors to use in the case statement.
