I would naively suggest that you or someone with knowledge of the method 
writes a set of unit tests and a comment, then someone who hasn't seen 
the method could implement it. Of course finding and ensuring someone 
hasn't seen the method may be impossible. And, many times the 
implementation may end up the same anyway.
