Not enough context to be useful, but it might be the best that can be  
done.  Calling a function and passing a bytes value allows the  
application to know that Python 2 str was encountered, and gives the  
application the opportunity to deal with it when the unpickling is  
done, or raise an exception.

I'd be happy if the "default" behavior on str values is to raise an  
exception, rather than ever making a guess silently.
