[issue39610] memoryview.__len__ should raise an exception for 0d buffers

[Stefan Krah]

Stefan Krah <stefan at bytereef.org> added the comment:

The change looks reasonable, but unfortunately this is a long-standing
behavior that originates from before the Python-3.3 memoryview rewrite.

It is also present in 2.7 (the previous implementation) and documented
in 3.3:

https://docs.python.org/3/library/stdtypes.html#memoryview


I think I documented it because it looked strange back then, too.
So I've to think a bit what will be affected and how this behavior
came into place.
