I can't speak for Jason, but for me, this is not very useful. I don't want to write in a Haskell DSL, I want to write in Haskell. And not the whole program, either, just the parts that really lend themselves to functional programming (parsers, numeric computations, code generators, various algorithms). Which means I need to be able to call Haskell functions from JavaScript.
This was what I was originally writing in about, yeah. However, thinking it over I realize there are some serious problems. We really do want to work with a restricted subset of Haskell that is more amenable to translation -- one with finite arrays and most every type translatable to JSON.
I'm not particularly concerned with non-strict evaluation, either. Strict is preferable wherever it would not alter the outcome.
I fear that requires us to know, statically, whether potentially infinite structures like lists are finite or infinite. I'm not sure about this but I suspect that's a major stumbling block. -- Jason Dusek
