From MyPy
error: Argument 1 to "crc32" has incompatible type "array[Any]"; expected "bytes"

This function does work with array.array() objects, so I assume its a bug?

@srittau as a type for buffer protocol is not available, should I just put array.array[Any]? Solves the problem for now.

That should be fine yes. Ideally the Any should be something more specific.
