I wasn't, but I wasn't pushing for it either.

Unfortunately, if we were to accept Raymond's proposal, we'd have to revisit the discussion, since his proposal removes several ways we currently avoid the need. In fact, I think Raymond's example is more properly considered an argument for adding a conditional expression than for removing the current behavior of the and/or shortcut operators; had we had a conditional expression, he wouldn't have tried to use the "x and y or z" syntax that bit him. Given this realization, I'm now -1 on Raymond's idea, and +1 on adding a conditional expression. I believe (y if x else z) was my favorite last time, wasn't it? I've changed the subject accordingly. -- --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
