JSON.stringify of a class instance, or of a record, array or union that
holds one, boxes the value and serializes it with the runtime JSON
traversal. The output matches Node: own enumerable properties in
creation order, properties added after construction, toJSON on the
instance or a base class, and no methods, accessors, #private fields or
static fields. A class whose declared field cannot be read through the
checked-dynamic property view, such as a Date field, is refused at
compile time with SC1090 naming the field.
Boxed Map and Set values now stringify as {}, as Node does, instead of
throwing.
