# In Python 3.2 JUMP_ABSOLUTE's (which can
# turn into COME_FROM's) are not optimized as
# they are in later Python's.
#
# So an if statement can jump to the end of a for loop
# which in turn jump's back to the beginning of that loop.
#
# Should handle in Python 3.2

#         101	JUMP_BACK         '16' jump as before to loop head
