I know what it does, but I question the wisdom of having it in the
standard. I don't think I've ever seen a call to Set_Input or
Set_Output outside a test program.
Yes, it can be handy to have a quick and dirty way to redirect default
input and output within a program, but I'd much rather use another
File_Type object or parameter than mess around with the global state
of Ada.Text_IO. After all, that's why there are versions of Put_Line,
Get_Line, etc. that take File_Type parameters.
