Any time a tuple is returned.

The problem I had with your code is that sometimes
you return a string and sometimes a tuple. So I
can only use argument unpacking when I get the tuple.
If I always get a tuple then I can always use unpacking.
Its the mix of incompatible return types that causes
problems.
