I have refrained from voting because in my line of work buffers or memoryviews deal with large objects that rarely serve as dictionary keys. As a result, I have zero experince with hashing of buffers. This observation supports the current consensus to limit hashing to 1d and 0d cases. My only concern is that with hash(m) == hash(m.tobytes()) implementing multidimensional restriction will require artificial if ndim > 1 check and an extra sentence in the docs while not simplifying anything. |
