PR 709 fixes the order of types for concatenating bytes and and bytearray. b''+0 will raise "can't concat str to bytes" rather than "can't concat bytes to str". PR 710 makes error message for str concatenation more informative and similar to error messages for list, tuple, deque, array. '' + b'' will raise "can only concatenate str (not "bytes") to str" rather than "must be str, not bytes".
