Comment (by RyanGlScott):

 Actually, this limitation applies to more than just empty lists:

 {{{
 $ ~/Software/ghc-8.2.0.20170507/bin/ghci -fprint-explicit-foralls
 GHCi, version 8.2.0.20170507: http://www.haskell.org/ghc/  :? for help
 Loaded GHCi configuration from /Users/rscott/.ghci
 λ> :type +v [1]
 [1] :: forall {a}. Num a => [a]
 λ> :type +v [1] @Int

 <interactive>:1:5: error: parse error on input ‘@’
 }}}

 So perhaps I was barking up the wrong tree in my investigation in
 comment:4.
