I don't understand this feature.... Hmm, Tokio Kikuchi asked about the name in 2005. I'm sorry that I didn't comment earlier. <https://sourceforge.net/tracker/?func=detail&atid=300103&aid=1347962&group_id=103> Sibling is a *completely* misleading term for this feature, because sibling relationships are necessarily symmetrical: if A is a sibling of B, then B must be a sibling of A. This feature is necessarily anti-symmetrical, more like "child" or "descendent". The term "sibling" will lead people to misconfigure their lists. <http://en.wikipedia.org/wiki/Symmetric_relation> <http://en.wikipedia.org/wiki/Antisymmetric_relation> Question: is the relationship also transitive? IE, if C is a child of B, and B is a child of A, then will postings to A go to members of C? If so, then the relationship should be called "descendent". <http://en.wikipedia.org/wiki/Transitive_relation> As far as inclusion is concerned, we then have a partially ordered set of mailing lists under this relationship. If the code handles the (presumably erroneous case) where a list is marked as a "sibling" of itself properly (ie, the listing should be ignored). <http://en.wikipedia.org/wiki/Partial_order> -- Ian Eiloart IT Services, University of Sussex x3148 _______________________________________________ Mailman-Developers mailing list Mailman-Developers@python.org http://mail.python.org/mailman/listinfo/mailman-developers Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-developers%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-developers/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
