Thinking of it, an alternative would be to implement lazy slices of bytes objects (Twisted uses buffer() for zero-copy slices).
Regards
Antoine.

Hello everyone and Benjamin, Currently, memoryview objects are unhashable: >>> hash(memoryview(b"")) Traceback (most recent call last): File "", line 1, in TypeError: unhashable type: 'memoryview' Compare with Python 2.7: >>> hash(buffer("")) 0 memoryviews already support equality comparison: >>> b"" == memoryview(b"") True If the original object providing the buffer is hashable, then it seems to make sense for the memoryview object to be hashable. This came while porting Twisted to Python 3. What do you think? Regards Antoine.
