*Can* be compiled with GHC 5.0, or *is* compiled? http://haskell.org/ghc/docs/6.8.1/html/users_guide/release-6-8-1.html says that the pointer tagging in 6.8.1 improves most code by 10-15%, "and as a result the compiler is also faster", implying that ghc-6.8.1 is used to compile itself. I'm just curious. -Brent
