Intuitively, what did you expect this to do? I don't see why a single message should be iterable. >I think that if any object (from standard library at least) doesn't support >iteration, it should clearly state so. That's going a bit far. Iteration is a relatively new addition to Python. Those classes that DO support iteration generally say so. If it isn't mentioned, you probaby shouldn't assume it. >Can this behaviour of email be considered a bug? Not in my opinion, no. >Is there a good case to iterate over something useful in a message? Well, if you don't have an answer to that question, then why would you expect it to support iteration? >P.S. rfc822 has the same behaviour, at least on Python 2.3 Again, I'm not sure what, intuitively, it would mean to iterate over an rfc822 object. -- - Tim Roberts, [EMAIL PROTECTED] Providenza & Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list
