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;
var
n: Struct;
begin
n:=Struct(0);
end;
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
TObject.
3) Variable name "val" (Use Value instead, there is a function called
val).
