Could you please elaborate on this (or give an explicit example how
might one do something bad unknowingly when returning multiple values in
a list)?
Should I think of tuples simply as a safeguard and reminder (because I
consciously use them for different thing than lists, as the faq
suggests)? Something similar to C++'s "const" (i.e. not strictly
necessary but useful for avoiding bugs)?
