I find that memoryview(b'abc')[::-1] is a strange thing to have,
anyway, so I'm not bothered by it behaving different. I can accept
that it needs to be supported for consistency, but I would recommend
against using it in applications. Who needs reversed memory, anyway?
The only case were I ever needed reversal is lists (typically sorted,
perhaps cronological).
