But of course Gnat /= Ada.

While I don't think any implementor would plan to raise an exception
from Is_Open, certainly the standard allows Use_Error or Device_Error
and of course Storage_Error and Program_Error (if there are elaboration
problems). In practice, I think it's safe to ignore that possibility.
