CPP11 — _var & _out types problems (01)

Summary: 1. The spec insection 20.9.2 does not specifically address the form of
T_out types for fixed length structured types. So, should the T_out
type be:

typedef T &T_out;

or should it follow the form of the T_out type for variable length
structured types and define as a "class T_out"? In this case, of course
the copy contructor operator from T_var would not delete the pointer
held by the T_var.

Since the "class T_out" solution for fixed length types does not appear
to have any advantages over the typedef, I recommend that the spec be
modified to state that T_out types for fixed length structured types
simply be a typedef of "T&".
