Something else the PEP needs to be updated to cover is that in 3.5+ (and maybe even in 3.4 - I'm not sure when 'c' support landed in memoryview) you can write the following efficient bytes iterator:

    def iterbytes(data):
        return iter(memoryview(data).cast('c'))

And use it as so:

>>> data = b"123"
>>> for datum in iterbytes(data):
...     print(datum)

That will then work with any buffer exporter, not just bytes and bytearray, and since it's a function, you can easily make a similar function that's polymorphic on str -> str iterator and bytes-like -> bytes iterator.
