The original issue was about different error messages in REPL and eval(). But
it is not related to string prefixes. We have the same difference without
involving strings:

Serhiy Storchaka added the comment:
array.array should copy the content, to be able to modify it. It implements
both the storage for data and the view of that storage.
What you want is already implemented as the memoryview object.
>>> import array
>>> x = array.array(&#x
Serhiy Storchaka added the comment:
Yes, it is a bug. __len__ can return a value different from the amount of bytes
(in array.array, memoryview).
len(buffer) can be replaced with memoryview(buffer).nbytes, but maybe we could
keep None and let the lower level to handle it.
