Comment (by barry):

 Totally agree that inputs should accept either (utf-8) str or bytes.

 Output could return a hybrid object that knows how to convert between
 (utf-8) str and bytes.  Very roughly something like the following:

 {{{
 def foo():
     return b'abc'

 def bar():
     return foo() + b'def'


 class BS:
     def __init__(self, some_bytes):
         self._value = some_bytes

     @property
     def str(self):
         return self._value.decode('utf-8')

     @property
     def bytes(self):
         return self._value

     def __str__(self):
         return self.str

     def __bytes__(self):
         return self.bytes


 v = BS(bar())
 print(repr(v.bytes))
 print(repr(v.str))
 print(repr(bytes(v)))
 print(repr(str(v)))
 }}}

 Users wouldn't have to write their own wrappers, but they'd have to be
 explicit about whether they wanted bytes or str in their own code.

 {{{
 % python3 /tmp/foo.py
 b'abcdef'
 'abcdef'
 b'abcdef'
 'abcdef'
 }}}
