with ghc 8.0.0.20160111, cabal install shake fails with [43 of 47] Compiling Development.Shake.Args ( src/Development/Shake/Args.hs, dist/build/Development/Shake/Args.o )
src/Development/Shake/Args.hs:1:1: error: solveWanteds: too many iterations (limit = 4) Unsolved: WC {wc_simple = [D] _ :: Eq a (CDictCan) [D] _ :: Ord a (CDictCan) [D] _ :: Read a (CDictCan) [D] _ :: Show a (CDictCan) [W] hole{a4gTO} :: a ~ a (CNonCanonical) [D] _ :: Eq a (CDictCan)} New superclasses found Set limit with -fconstraint-solver-iterations=n; n=0 for no limit Is this a known problem?
