Comment (by RyanGlScott):

 This might possibly be related: running the following command in GHCi
 yields an error:

 {{{
 $ ghc/inplace/bin/ghc-stage2 --interactive
 GHCi, version 7.11.20151219: http://www.haskell.org/ghc/  :? for help
 λ> :set -XTypeInType -XRankNTypes
 λ> :kind! forall (a :: k). 'Just a

 <interactive>:1:14: error:
     • GHC internal error: ‘k’ is not in scope during type checking, but it
 passed the renamer
       tcl_env of environment: []
     • In the kind ‘k’
       In the type ‘forall (a :: k). Just a’
 }}}

 Yet putting it into a module makes it compile without issues:

 {{{
 {-# LANGUAGE RankNTypes, TypeInType #-}
 module InternalError where

 type T = forall (a :: k). 'Just a
 }}}
