So i would hope for '.all_defects[]' and (policy-adjusted) '.defects[]'. I would hope for '.had_header_defects(policy_only=True)', '.had_payload_defects(policy_only=True)'. Doing so would fill the huge hole in between 'not len(defects)' and the detailed inspection of a defects list which consists of a highly differentiated tree of classes. The parser has to parse- and does encounter all of these anyway, and an application cannot re-collect this (dropped) information except with expensive effort, i.e. at least choosing a different, stricter policy followed by another parse of the bogus mail. In the end it is my believe that a framework should bring light onto all aspects of a thing, such that no other framework is ever needed, but especially not on a lower level (except the framework is so designed that it allows replacement of its own low-level interface, say). And i don't think there can be a higher level interface than message_from_(bytes|string)(). _______________________________________________ Email-SIG mailing list Email-SIG@python.org Your options: http://mail.python.org/mailman/options/email-sig/archive%40mail-archive.com
