From Ada.Text_IO? No you cannot, File_Type is not tagged. For a stream
you could.

I would say that one should never use anything but Put_Line and never
instantiate any I/O packages. First format an output line in a string,
and then output the string.
I would suggest to define logging/tracing package, instead of doing
direct output. It always pays off.
