[Python-ideas] BUG in standard while statement

I found a BUG in the standard while statement, which appears both in python
2.7 and python 3.4 on my system.
It usually won't appear because I only stumbled upon it after trying to
implement a nice repeat structure. Look:
def __init__(self, n):
self.n = n
self.n -= 1
return self.n >= 0
a = repeat(2)
the meaning of the above is that bool(a) returns True 2-times, and after
that always False.
will in fact print 'foo' two times. HOWEVER ;-) ....
will go on and go on, printing 'foo' until I kill it.
Please comment, explain or recommend this further if you also think that
both while statements should behave identically.
hoping for responses,
