Yes. Do a use immediately after declaring the object:
declare
State : Doodah.State_Value_Type;
use Doodah;
begin
<literals are now directly visible>
State := State_0;
end;
The idea is that you want to be able to trace an entity back to the
source. Since you've stated explicitly that State_Value_Type is
declared in Doodah, there is high probability that State_0 is declared
there too.
