Did `:kind!` ever expand synonyms?
The user manual claims that it does, but I can see no evidence that it ever did.
It did in GHC 7.8.4: {{{ GHCi, version 7.8.4: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... done. λ> type A = () λ> :kind! A A :: * = () }}} But not in GHC 7.10.3: {{{ GHCi, version 7.10.3: http://www.haskell.org/ghc/ :? for help λ> type A = Bool λ> :kind! A A :: * = A }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13795#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
