I submitted the bug report before considering this alternative, which is better. I may add this later in the day, but I have to wait a little as it seems you are going to optimize/improve the function almost out of existence:) If you are happy with this one, and can add the comment on the issue (http://bugs.python.org/issue7764) yourself, please do so. What I can say is, I am definitely very happy that I asked the question. You live and learn:) Cheers, Muhammad -- http://mail.python.org/mailman/listinfo/python-list
