How do you see the relationship between (current-output-port)
and (standard-output-port)?

If as currently specified we have that (current-output-port)
is initially bound to (standard-output-port), then you have the
problem that you've just broken "hello world":
   (display "hello world")

We really don't people to have to deal with transducers just
to write hello-world-level programs.

One possible approach is that (current-output-port) gets
lazily initialized to a textual stream bound to (standard-output-port),
on first use.
