New submission from tormen <tormen at gmx.net>:

# python 3.1.1:

myList = []
for item in myList:
    print( item ) # <<< works

for item in myList.reverse(): # <<< breaks with: TypeError: 'NoneType' object is not iterable
    print( item ) #

# But the reverse of an empty list should really be an empty list
# ... or do I miss something here?
