So when you ask the user something as the application is running, you should print the question on stderr? That doesn't sound right. Do you have a source for it? Does this only apply to applications which have output other than just questions and responses (output the user might want to pipe somewhere)?

@UTF-8 Should the text of the question be considered part of the output of the program? What about that which the user types in? I don't think it should be (just like shells don't think it should be). But maybe it depends on the application?

Thank you for your edit. In the meantime, I checked the behavior of standard applications and they behave like one would expect them to behave after reading your answer.
