Comment:

 OK, I was able to work around #13804 by adding `{-# LANGUAGE
 NoMonoLocalBinds #-}` to the appropriate file in `ivory-bsp-stm32`. I was
 then able to build `clock` (and run `blink-test`) without any issues on
 GHC 8.2.

 I think this is as good of a confirmation as we're going to get that the
 issue experienced here has been fixed, so I'll close this ticket.
