It does not directly answer your question, but are you aware of Pie? https://github.com/david-christiansen/pie-hs On Thu, Jun 20, 2019 at 1:45 PM Andrew Martin <andrew.thaddeus@gmail.com> wrote:

I just read through Lennart's paper on Cayenne, which was written in Haskell. It would be informative for me to look at the source code for a simple dependently typed language like this.

Has it been devoured by the cruel jaws of the ephemeral web, or does someone out there still have a copy of it?
