      slice cannot be hashed which make some operations significantly more annoying. see https://groups.google.com/forum/#!topic/comp.lang.python/SvhkWwSDeIw

      Please re-upload the patch file as an uncompressed text file, as it is quite difficult for many people to view zip files in their browser.

      Thank you for fixing this.

      For anyone who was wanting hashable slices, my library ndindex may be of interest. It has a hashable Slice object but it also does a lot more like slice arithmetic which may be useful for a lot of the use cases described here.
