We only want to change owner of the symbol I create, right? Not the system unit ones? If not changing owner maybe we need to add some ref count or something? just confirming to make sure.

Also it looks like ChangeOwnerAndName isn't making the compiler happy.

The dynamic array creates an unnamed typesym like this. (def is the array def for [1,2,3])

              newtype:=ctypesym.create(def.typename,def);
              newtype.owner:=def.owner;

And specialized like this:

generic procedure DoThis<T>(p1: T);
begin
end;

begin
  DoThis([1,2,3]);
end;

Then during assembling I get these errors.
