No, I mean that the Mat structure has a MatSize MatStep member 
with pointers to the struct data itself.

Until we have copy ctors, D can't have structures with internal 
pointers, as they can be moved... that's something similar in C++ 
string, if I remember well, and that was the blocker that leaded 
to the copy ctors DIP...
