I'm thinking of removing the lambda. I'm not using it, and I can no longer see a need for it. I thought it was necessary because my initial stringification mechanism didn't automatically quote strings, so (1,'(2, 3)') would stringify to the same as (1,(2,3)).

Now that I am using the str() function as the default lambda, this is no longer the case - you get (1, '(2, 3)') and (1, (2, 3)) which are distinct.
