Admittedly the input is nonsense, but as `*` has no arguments, according to the March Hare, it can't have one fewer argument. Note that the second error does not contain this problematic line. {{{ rwbarton@morphism:/tmp$ ~/ghc-newest/inplace/bin/ghc-stage2 --interactive GHCi, version 7.11.20151228: http://www.haskell.org/ghc/ :? for help Prelude> import Data.Kind Prelude Data.Kind> :set -XTypeApplications Prelude Data.Kind> :t fmap @ (*) <interactive>:1:8: error: • Expecting one fewer argument to ‘*’ Expected kind ‘* -> *’, but ‘*’ has kind ‘*’ • In the type ‘*’ In the expression: fmap @* Prelude Data.Kind> :t fmap @ Int <interactive>:1:8: error: • Expected kind ‘* -> *’, but ‘Int’ has kind ‘*’ • In the type ‘Int’ In the expression: fmap @Int }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11313 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
