Comment (by RyanGlScott):

 I must be doing something wrong here. I created a file named `Bug.hs` with
 the contents of comment:2, and tried loading it like so:

 {{{
 $ ~/Software/ghc-8.4.1/bin/ghci -fdefer-type-errors -ignore-dot-ghciGHCi,
 version 8.4.1: http://www.haskell.org/ghc/  :? for help
 Prelude> :load Bug
 [1 of 1] Compiling Main             ( Bug.hs, interpreted )
 Ok, one module loaded.
 }}}

 Which appears to work without issue. What am I missing?
