If you simply want to bind the current input/output port to string,
you can do the following:

(with-input-from-string "hello"
  (lambda ()
    (with-output-to-string
      (lambda ()
        (display (read))))))

In this example, `read' reads the contents of the string "hello" and
`display' writes its output to a string, which is then returned.
