The new approach is a response to the devs and to Sasha who had some
relevant comments. Yes, I agree that many devs don't "get" how useful
it would be because they have not written scientific or
graphics-intensive applications. However, Guido is the one who
encouraged me at SciPy 2006 to push this and so I think he is generally
favorable to the idea. The Python devs will definitely push back. The
strongest opposition seems to be from people that don't 'get' it and so
don't want "dead interfaces" in Python.
They would need to be convinced of how often such an interface would
actually get used. I've tried to do that in the rationale, but many
people actually posting to python-dev to support the basic idea (you
don't have to support the specific implementation --- most are going to
be uncomfortable knowing enough to make a stand). However, there is a
great need for people to stand up and say: "We need something like this
