Benjamin Peterson <benja...@python.org> added the comment: I think being able to catch exception with ABCs is esssentially useless. The originally stated "usecase" can be simply solved by putting classes into a tuple and putting that in the except clause.
In general, the whole abc machinary causes lots of code which expects instance and subclass checks to be side-effect free to be able to execute arbitrary code, which creates messes. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12029> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
