As a demonstration, here's an experiment with older technology, when
pipes were still made of wood (pre-splice):

 mkfifo /tmp/foo
 cat /tmp/foo >/tmp/foo

You may launch the real thing now with a simple

 echo Hello World >tmp/foo

Warning: with only one pipe, you're likely to bend the pipe too far,
and it may break (SIGPIPE).
