They're so trivial it would be better to reimplement than reuse. :-)

Ok - that's a reasonable request. Can you raise an issue for it?

That's in unittest in Python 2.7 - so I doubt it will be removed / 
moved. :-)

I don't understand what you mean by this. What are you trying to compare 
and why is the output not good enough?

Hmmm... sorted_list_difference is not used anymore, in fact I'm not sure 
why it was in a released version of Python in the first place. There was 
a variant of these in Python 3.1, but they were buggy and improved. I 
wouldn't rely on sorted_list_difference continuing to exist - it should 
be deprecated and removed.
