Performance regressiion?

I am seeing the following performance regression on OS X x86_64: cd ./perf/compiler && $MAKE -s --no-print-directory T4007T4007.run.stdout 2>T4007.run.stderr max_bytes_used 5428072 is more than maximum allowed 500 *** unexpected failure for T3064(normal) Is this specific to OS X x86

Indexed constraint families

Folks Max has just pushed a patch that adds a major new feature: indexed constraint families; see http://hackage.haskell.org/trac/ghc/wiki/KindFact Internally, a big change is that there is no PredTy any more. So TypeRep has gotten simpler (hooray). Julien, Dimitrios: this will conflict wit
