Oops, you didn't parser the above sentence correctly.
What 3.05 adds is "polymorphic methods" and "polymorphic record
fields", but not "polymorphic records" (you still have to simulate
them with objects). Polymorphic record fields are shortly described
in the core language part of the tutorial; they provide explicit
polymorhism at the record field level, which may be light than going
through objects and methods.
