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 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.
