From dc6b2b438236ed89c624e9c0bb035cc8321149cc Mon Sep 17 00:00:00 2001 From: Sebastian Spaeth Date: Tue, 9 Aug 2011 17:48:27 +0200 Subject: [PATCH] python: remove Tags().__len__() implementation len() exhausts the tag iterator and e.g. list() or "".join(tags) implicitly call len() if existing and then failing. So, we remove Tags.__len__(). If you need to know the number of tags a message has, do use len(list(tags)). It would be nicer to be able to support len() directly...
