Not sure I agree on that. A function may, for example, print something
the user is interested in (e.g. some sort of hypothesis test) and offer
a return that is only of interest to experts (say, a vector of
relatively "raw" values that could be further processed).
Why should the GUI user be forced to assign the return, when the script
user is free to ignore it?
