Ehh, mea culpa (I shouldn't post in haste). Replace "Actually, yes you
do" with "Actually, yes they do". Indeed you do not *go shopping* with
a list of zero items; but a shopping list with no items on it DOES
exist (when you come back).
def do_shopping():
if shopping_list:
goto shop; # Muahahahahaha.
for item in shopping_list:
inventory.append(item)
return; # Muahahahaha again!
