Comment (by JulianLeviston):

 Yeah, ok, sorry I was reading
 https://ghc.haskell.org/trac/ghc/ticket/15646#comment:16 by mistake... I
 also thought desugaring wasn't part of type-checking. In the diagram it
 happens after type checking. For some reason I'd assumed once it'd type
 checked the expression it would stop.

 Ok I can easily refactor that.

 Yeah I didn't submit to Phabricator yet because I knew it was obviously
 wrong. Thanks for correcting me. I'll give it another shot. Again, thanks
 for all the help, I really really appreciate it, and hope to repay by
 hopefully being able to fix bugs more easily with the next ones.
