Thanks! Actually I am convinced that Hamlet is the best template language for real-world designers because it is just HTML. Our reports back from designers have all been very positive. For Haskell Hamlet (there is a Ruby & JS version) certainly manipulating Haskell code is different that what they are used to, but that has little to do with Hamlet. There is an advantage however: they get an error message right where the error is at compile time rather than having to trace things at runtime.
