Comment (by Richard Eisenberg <eir@…>):

 In [changeset:"972730cc42a419b8cd148abaa927e03415da3a68/ghc" 972730c/ghc]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="972730cc42a419b8cd148abaa927e03415da3a68"
 Refactor visible type application.

 This replaces the old HsType and HsTypeOut constructors
 with HsAppType and HsAppTypeOut, leading to some simplification.
 (This refactoring addresses #11329.)

 This also fixes #11456, which stumbled over HsType (which is
 not an expression).

 test case: ghci/scripts/T11456
