I need some help here.

No, that's not quite what I meant. Your class (cl) would look like this:

class cl{
     private:
         char[][] _data;
         int _maxDataLength;
     public:
         MyArray!(MyArray!(char)) data() {
             // Construct a MyArray which represents a readonly view of 
the data
         }

         int maxDataLength(){
             return _maxDataLength;
         }
     private:
         int calculateMaxDataLength(char[][] data){
             // this takes time.
         }
}

The constructor would be annoying to write, though, because you would 
need to recursively generate one for each level of the array. However, a 
bit of template magic could be your solution here, I think.

Yes, from your other post, const is really what you need, and many 
people find it lacking. However, it is way too complex to rush, and 
there has not yet been a perfect solution proposed. There probably never 
will be, so D may remain without const.
