Ok, sorry all for the delay. Attached is a "frontend plugins" patch for ghc 7.4.2. It will not work for ghc HEAD because the structure of the compiler has changed in various places, but I cannot currently compile my code against HEAD. Making this available now because it's been far too long already :) Comments/suggestions/feedback welcome. Hopefully the patch is pretty self-explanatory; and it's only small.
