Because it is not len(b). I fixed several bugs in Python code which called 
len() for bytes-like argument and failed with array.array or memoryview with 
non-byte items.

The term "bytes-like object" is slightly misleading. In some cases it implies 
indexing and len, and iterating, and may be slicing -- common operations for 
bytes, bytearray, array('B'), memoryview().cast('B'). In more narrow meaning 
it may require such operations as concatenation (operator +) and .startswith() 
-- common for bytes and bytearray. In more general meaning it requires only 
the support of buffer protocol and contiguity. In more general meaning it may 
be even non-contiguous.
