How about directly using the existing "copy.copy()" semantics instead of self._recreate()? That is, call "with copy.copy(self)" instead of "with self" in ContextGenerator.__call__(), implement ContextGenerator.__copy__() method to simply return self, and implement _GeneratorContextManager.__copy__() to create a copy of itself. This saves an internal interface. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11647> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
