Standarize GHC.Prim.Any

I'm so sorry if I've done it wrong - it's my first contact with Haskell standardization and I base on http://hackage.haskell.org/trac/haskell-prime/wiki/Process . I hope it is not too late as well. Any from GHC.Prim makes unsafeCoerce much useful and safe. Can it be included in Unsafe.Coerce module? Pros: - unsafeCoerce is much more useful with Any (it's a safe placeholder for any value and therefore can be passed simply in/out FFI). Cons: - unsafeCoerce is useful, but not very nice, platorm-dependent low-level anyway. Best regards
