   Sorry if I wasn't clear. I didn't meant neither that 'auto g = f;' is   
   an assignment not that lambdas should support assignment (I don't have   
   an opinion on that).   
      
   Since the topic is about assignment, I should have written 'auto   
   g(f);' to avoid the misunderstanding.   
      
   All I wanted was to give an example showing that it's possible to have   
   two distinct objects (objects with different addresses) of the same   
   closure type.   
      
   Thanks,   
   Cassio.
