After the numpy-discussion thread about np.matrix a week or so back, I got curious and read the old PEPs that attempted to add better matrix/elementwise operators to Python. http://legacy.python.org/dev/peps/pep-0211/ http://legacy.python.org/dev/peps/pep-0225/ And I was a bit surprised -- if I were BDFL I probably would have rejected these PEPs too. One is actually a proposal to make itertools.product into an infix operator, which no-one would consider seriously on its own merits. And the other adds a whole pile of weirdly spelled new operators with no clear idea about what they should do. But it seems to me that at this point, with the benefit of multiple years more experience, we know much better what we want -- basically, just a nice clean infix op for matrix multiplication. And that just asking for this directly, and explaining clearly why we want it, is something that hasn't been tried. So maybe we should try and see what happens. As a starting point for discussion, I wrote a draft. It can be read and commented on here: https://github.com/numpy/numpy/pull/4351 It's important that if we're going to do this at all, we do it right, and that means being able to honestly say that this document represents our consensus when going to python-dev. So if you think you might object please do so now :-) -n -- Nathaniel J.
