That answers most of my worries. I'll leave this to sink in for a few days; but I'll start brainstorming for shorter syntax alternatives which might make this discussion shorter :-) Here's some starting points you all won't like: int[:].cwise int.cwise[:] Also consider that "array" is already a Python builtin doing much of what Stefan seems to be after, at least Python side. array[int] should perhaps at least be an alias for what Stefan wants int[:] to be, at least in 1D, although Stefan's arguments from "expectation of random Python user" is still valid. (BTW, this is how a 2D arrays look in Fortran, which is still a very dominant tool in numerics: real, dimension(:,:) :: arr So you can see where my inspiration with the [:] came from.) -- Dag Sverre _______________________________________________ Cython-dev mailing list Cython-dev@codespeak.net http://codespeak.net/mailman/listinfo/cython-dev
