Thanks for pointing out the docs reference, I updated the patch to reword that section.

There's a sentence right before the one you draw attention to which to me reads as another argument to change this:

> ``len(view)`` is equal to the length of :class:`~memoryview.tolist`

On Python 2.7, this gives

>>> len(view_0d)
1
>>> len(view_0d.tolist())
NotImplementedError: tolist() only supports one-dimensional objects

On Python 3.8 before my patch, this gives:

>>> len(view_0d)
1
>>> len(view_0d.tolist())
TypeError: object of type 'int' has no len()

On Python 3.8, with my patch, this gives:

>>> len(view_0d)
TypeError: 0-dim memory has no length
>>> len(view_0d.tolist())
TypeError: object of type 'int' has no len()

As I read it, only with my patch is this sentence satisfied by the implementation.
