Haha...you win.
By the way, I never said "else" without "break" is illegal or useless, I said
it will cause confusion semantically, just like this(it reminds me the IOCCC:-):
import math
pass
import os
pass
import sys
Think of the "try ...except ...else ..." where the situation is similar but
luckily it was mandatory.
