See Note [TYPE] in TysPrim. There are still some outstanding pieces in #11471 though, so this doesn't actually nail the bug. This commit also contains a few performance improvements: * Short-cut equality checking of nullary type syns * Compare types before kinds in eqType * INLINE coreViewOneStarKind * Store tycon binders separately from kinds. This resulted in a ~10% performance improvement in compiling the Cabal package. No change in functionality other than performance. (This affects the interface file format, though.) This commit updates the haddock submodule. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11471#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
