Is this a well known bug that's been fixed?
I couldn't find any discussion of it, but maybe my googling's off today ;-/
... it = iter(range(10))
... while True:
... i = it.next()
... print i
... if i&3==0:
... print 'skipping next'
... it.next()
...
------------------< This looks ok: 0
skipping next

Traceback (most recent call last):
File "<stdin>", line 1, in ?
... i = it.next()
... print i
... if i&3==0:
... print 'skipping next'
... it.next()
...
-----<this doesn't look ok: it.next() is apparently not doing anything:

I guess it could be in the read-eval-print loop
I have an old 2.4 on NT4 and am running it in a console window.
