Comment (by lwm):

 bgamari, thanks for the input.

 No, that's pretty much exactly what happened to me. I didn't get as deep
 as you did with regards to the desugared output. I have since been playing
 with trying to run doctest against base.

 I think I will get some logs to illustrate the problem and create an issue
 over at the doctest repo. It's definitely been blocking me. Otherwise, do
 you have some recommendations?
