Not very likely. I'm much more enthusisatic about Template Haskell just now, which lets you do similar things in a different way, and much more besides. See my home page http://research.microsoft.com/~simonpj I'm getting on with the implementation. If you are interested, check out the meta-haskell-branch of the CVS tree. It'll become the HEAD as soon as I'm sure I haven't broken anything badly, and thence get into a release. Meanwhile, constructor and field names for Derivable Type Classes languish, I fear.
