Why do you not change the list into a tuple and return the tuple, and let
automatic unpacking handle it?
As I see it, the problem is not in the return, but in the call - how do you
know now, which of the following to write:
answer = thing(params)
answer0,answer1 = thing(params)
answer0,answer1,answer2 = thing(params)
answer0,answer1,answer2,answer3 = thing(params)
and so on...
probably best to write:
answers = thing(params)
for answer in answers:
do something with answer
