Oh. Well then, good call. :)

I've got Atomo up and running on GHC 7 now. Very nice performance
boosts! Plus memory appears to be freed, though I can't test loading
as it panics:

    atomo $ atomo
    > load: "src/empty.hs"
    atomo: atomo: panic! (the 'impossible' happened)
      (GHC version 7.0.0.20100924 for i386-apple-darwin):
    	Testing for extension flag Opt_Generics before flattening

    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

Daniel: I've attached a patch containing the changes I made to Hint to
get it compiling (though not working apparently) on GHC 7. Hope it
helps!
