Maybe a Put_Immediate could be provided for the equivalent simplicity of
output?

I wonder if it might be an idea to slightly read the existing RM :-)

9   procedure Get_Immediate(File : in  File_Type;
                            Item : out Character);
    procedure Get_Immediate(Item : out Character);

        10   Reads the next character, either control or graphic, from the
        specified File or the default input file.  Mode_Error is propagated
        if the mode of the file is not In_File.  End_Error is propagated if
        at the end of the file.  The current column, line and page numbers
        for the file are not affected.


As for Put_Immediate, stream output to standard output has the effect
you want, I see no reason to decorate Text_IO with more stuff!
