The september 95 Working draft 8.3.1 says:

"A reference shall be initialized to refer to a valid object or function."

What is a valid object ? I can't find a good decription of that in
the draft. Is it:

1. An object that has storage.
2. An object which constructor has executed.
3. A typo ?
4. An out-of-date sentence in the draft.
5. None of the above ?

Example code from gnu.g++.help:

>#include <iostream.h>
>
>class Foo
>{
>public:
>  Foo (int size_arg = 0) : size (my_size), my_size (size_arg),
>    values (new double [size]) {}>
  ~Foo () { delete values; }
>  int const& size;
>private:
>  int my_size;
>  double* values;
>};

Is this code correct C++ code or not ?

Or must one change the order of the member variables in the
class so that my_size is before size  and get to be intialized 
first ?

And what will happend if they not are integers but actuall classes
with constructors ?
