What are the odds of this thing going in?
I don't know. Guido has said nothing about it so far this time round, and his is the only opinion that matters in the end. I may write a PEP about this. However, since yesterday I've realised that there's a rather serious problem with part of my proposal. The problem is that being able to multiply matrices isn't much use without also being able to add them and multiply them by numbers, which obviously can't work with the built-in sequence types, since they already have other meanings for + and *. However, I still think that adding an @ operator for numpy to use is a good idea. So I'm now suggesting that the operator be added, with the intended meaning of matrix multiplication, but that no implementation of it be provided in core Python. There is a precedent for this -- the ellipsis notation was added purely for use by Numeric and its successors, and nothing in core Python attaches any meaning to it.
How do the PEPs work?
Someone writes a PEP. People talk about it. Eventually, Guido either accepts it or rejects it (although in some cases it is an infinitely long time before that happens:-). -- Greg _______________________________________________ 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
