Issue 1624:  Forward declaration of value boxes (obv-rtf)
Source:  (, )
Nature:  Revision
Severity: 
Summary: Summary: It is not clear from the spec whether or not value boxes can be 
 forward declared, and used recursively.  For example,
 
     value v;
     struct s {
         long s0;
         v next;
     };
     value v s;
 
 If value boxes are indeed syntactic sugar, the answer should be yes.
 That brings the next question: Does this mean that one can call
 create_box_value_tc(), supplying NULL for the original_type, and
 then later on fill in the member typecode via fill_in_recursive_tc,
 supplying a ValueMemberSeq of length 1?

Subject: Forward declaration of value boxes

It is not clear from the spec whether or not value boxes can be 
forward declared, and used recursively.  For example,

    value v;
    struct s {
        long s0;
        v next;
    };
    value v s;

If value boxes are indeed syntactic sugar, the answer should be yes.
That brings the next question: Does this mean that one can call
create_box_value_tc(), supplying NULL for the original_type, and
then later on fill in the member typecode via fill_in_recursive_tc,
supplying a ValueMemberSeq of length 1?
