Not necessarily a bad idea, it's just that the way to get a no-echo
input is tricky.  You *can* do it with iostreams, but you need to call
a termios function to switch the console into no-echo mode.

See the node "Termios Functions" in the library reference manual, for
more about this.  Using termios is better than conio, because termios
functions are supported on Unix and GNU/Linux systems.
