Assuming by "them" you mean the value of EXPR and the value assigned to VAR, I don't care how this conclusion is reached, as long as their separation is seen as a useful thing. :-) I came up with the idea of making them separate when I tried to figure out how to decorate a generator to drive a PEP-310-style with-statement, and found I couldn't do it for the opening() example. (Michael Hudson illustrated this nicely in his reply in this thread. :-) But it's fine if the separation is considered generally useful even without thinking of generators. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
