It's not "accepted as acceptable", it's just a side effect of how various means of iterating (including for loops and generators) are implemented in CPython. Seeing how it doesn't seem to prevent or promote any useful programming idiom, there was no incentive to either 1) codify it as official spec or 2) change it. In other words, it should be considered undefined behaviour, and perhaps other Python implementations behave differently. Regards Antoine. -- http://mail.python.org/mailman/listinfo/python-list
