For example, consider the behaviour of:
condition = False
if condition:
print "true"
else:
print "false"
and
condition = False
while condition:
print "true"
break
else:
print "false"

Then:
i = 0
while i < 10:
print i
i += 1
else:
print "Done!"
for i in range(10):
print i
else:
print "Done!"
So for/else behaves while/else, hence for/else really is the same way
round as if/else. It may not be "intuitive", but it's consistent, and
personally I'd rather have that.
