Apart the memory leaks wich are quite sure on purpose, you are using a
loudspeaker calling for problems in the future:

1) Constructor with the same name as class name. If you write in code:

procedure Struct.DoSomething;
  n: Struct;

Which should the compiler do ? Create a new object n calling the Struct
constructor using 0 as parameter, or cast zero to n ?

2) 2 constructors, one works the other simply does nothing. You can
not "hide" the constructor "Create" as you are inheriting from
3) Variable name "val" (Use Value instead, there is a function called
