New submission from Andrey Paramonov <paramon at acdlabs.ru>:
Currently, memoryview values can be assigned from all bytes-like objects (https://docs.python.org/3/glossary.html#term-bytes-like-object) except byte array.array:
----
import array
mview = memoryview(bytearray(b'hello'))
mview[:] = bytes(b'hello') # success
mview[:] = bytearray(b'hello') # success
mview[:] = memoryview(b'hello') # success
mview[:] = array.array('b', b'hello') # fail
----
mview[:] = array.array('b', b'hello')
ValueError: memoryview assignment: lvalue and rvalue have different structures
----
