A real object of a class-wide type needs to have a tag,
hence if you don't initialize, which tag should it be?
Solution:
Declare variables or constants where you need them,
and where you have assembled everything necessary for their
initialization. That is,

procedure simple_case is
   ...
begin
   ...
   declare
      var_x: General_T'class := <your initialization here>;
   begin
      op(var_x);
   end;
   ...
end simple_case;
