io.read() and io.write() default to stdin and stdout, respectively.
there's also io.stdin, io.stdout and io.stderr, which are file objects
already open, you can read/write there.

finally, in Linux you can open /dev/stdin and /dev/stdout and you get
a new handle to stdin and stderr, handy to use with any program that
gets a filename.
