Re "raise ValueError from ..." So what does it mean now? Just resetting __cause__ to make __context__ printed? Can you show the down-to-earth snippet of code where such syntax would be useful?

I kinda like the second - it feels more self-descriptive to me than "from Ellipsis" - but there's the counter-argument that it could look like noise, and I think would require a grammar change to allow it there. > > raise Exception() from ... > > is... well, I am now gleeful -- especially since I went to my fresh copy of Python 3.3.0a0 and did this: > > --> ... > Ellipsis > > --> raise ValueError from ... > Traceback (most recent call last): > File "<stdin>", line 1, in <module> > ValueError > > Have I said lately how much I *love* Python? > > ~Ethan~ > _______________________________________________ > Python-Dev mailing list > Python-Dev at python.org > http://mail.python.org/mailman/listinfo/python-dev > Unsubscribe: http://mail.python.org/mailman/options/python-dev/yselivanov.ml%40gmail.com
