The memoryview skeleton did not correctly assign the "obj" attribute; The "obj" attribute was assigned to the memoryview class and not the memryview object, leading to a funny bug that can be reproduced as follows: ```python m1 = memoryview(b'1234') m2 = memoryview(b'abcd') print(m1.obj) ``` the result would be the value inside `m2` instead that of `m1`
