Ok, If so you do not need to suppress exception, let it go further if it is occured in Close.

Yes, I miss a bit "final" Borland Delphi reserver word too, but I think it is not big deal. You could have a local procedure for the finalization of Local allocated resources, and call it twice, from end of procedure and in the exception handler. Maybe Ada200X would have a something like "final" in Borland Delphi. Is there somebody who think that the syntax like

declare
   Resource : Resource_Type;
begin
   Open (Resource);
   Use_This (Resource);
exception
   when Constraint_Error => Do_Something;
final
   if Is_Open (Resource) then
     Close (Resource);
   end if;
end;

Is bad or not safe ?

Where block from "final" to "end" would be executed in both cases, normal and any-exceptional.
