        1) Type families, associated types, synonyms... can anything replace the use of TypeCast for explicit instance selection? Section 2, bullet 4 of http://www.haskell.org/haskellwiki/GHC/AdvancedOverlap indicates a negative response. Any other ideas? 2) Any progress/options for kind polymorphism in instances? Thanks for your time.
