   No---at least the current draft doesn't specify one, keeping with
   Scheme's tradition here.

Actually, it does give an order.  "Parent init expressions, if any,
are evaluated before child init expressions."

   I don't think there's a way to get one.

It depends on whether or not the 'init' expressions count
as initializing the records.

By the way, in what context are the <constructor argument>s in

  (parent <parent name> <constructor argument> *)

evaluated?  Specifically, do they have any access to the values
passed to the subtype constructor?
