[Template-haskell] new TH tutorial (request for comments)

hi, (excuse the repost, but i guess my last post wasn't presented in a way that would readily incite responses...) i've recently written a tutorial on template haskell located at (http://www.haskell.org/hawiki/TemplateHaskellTutorial). it contains examples of loop unrolling, code transformation, etc and i would very much appreciate any feedback or corrections. thanks a lot, Johannes Ahlmann
