pd.lib.infer_dtype infers bytes in Python3
ping!
 ?
 @jreback ok with this?
 oh whoops, need to add tests for strops
 and add to this line: https://github.com/pydata/pandas/blob/master/pandas/core/base.py#L522

(test if you can)

squash as well. thxs
 ok, in progress
 hm, so to really be solid about this we'd have to test every single str operation against a bytes series

e.g., `cat` was failing because it has a `sep` argument that is `''` if  `None` is passed in. That string will be a unicode string in python 3 which can't be used with a `bytes` object
 Do we have to support `bytes` operations? I really just wanted the ability to tell if a `Series` contained `bytes`. I wasn't looking to add any new features.
 no I don't think bytes are necessarily a big deal to support - in fact prob should raise on str type ops?
 ok, i'll test that we raise on `str` access
 ok, looks good. just add a release note and merge. ty.
