[Tutor] Recursively flatten the list

" A more important problem is that it is flattening only one level.
Multi-level flattening is I think not possible without using some kind
of recursion."

Not true, just requires more iterations to check each element. Each iteration could check if every element is a list and then unpack if it is a list. When you finally have an iteration that has no lists, you can end the loop.

Not time efficient or pretty but it would certainly work without recursion.  I am sure people on this list can provide a better answer than I can :)
