When I first looked at this a year ago, I thought it seemed like a reasonable idea and might be useful.  Since that time, I've haven't encountered any situations whether this would have improved my or someone else's code.  And now, I can't even dream up any scenarios where ``operator.subscript[3:7:2]`` would be better than ``slice(3, 7, 2)``.   Accordingly, I think we should re-evaluate whether there is any real benefit to be had by adding this to the standard library.  Perhaps, we're better off without it.
