Sorry, I'll try to reformulate:
The terms "stdout" and "stderr" come from the Unix world. Each
process has one standard output and one error output. ls(1) can have
only two side-effects: writing to stdout and/or stderr.
But the above processor has three outputs: "stdout" (I guess it is
the standard output of the process), "stderr" (I guess...) and an other
one, "result". What is the value of this output, if it is not taken
from neither stdout nor stderr?
I hope that is a little bit clearer. Sorry for my too approximate
English :-(
