defined in CDuce we cannot do the same for CDuce record expressions
which require non-trivial modifications for occurrence typing,
especially because we want to capture record field extension and field
deletion which current radual typing systems fail to capture. CDuce record types are obtained by extending types with the
deletion which current gradual typing systems fail to capture. CDuce record types are obtained by extending types with the
following two type constructors:\\[1.4mm]
