Thank you very much for coming back and posting this resource! I will be 
reading it carefully and I'm already sure there is a lot of useful content! 
Much appreciated.

The "free online resource" I alluded to earlier is up on my Web page now.

https://cs.uwaterloo.ca/~plragde/flaneries/LACI/

I call it a "flânerie", but it's a mini-textbook on logic and proof 
assistants, using Racket to first construct a small proof assistant 
(Proust), expanding it to handle propositional and predicate logic, and 
then moving into discussion of the much larger Agda and Coq systems. --PR

Dear Prof. Ragde,

Thank you very much for the reply! I watched your talk at the Racket con 
more carefully today and noticed you specifically point out that you don't 
give your students the whole code and that the entire project is presented 
as a "proof of concept" and used especially for didactic purposes.

I totally appreciate this approach and I have to say I don't feel quite 
prepared to fill in the details myself. So I'm doing my best to learn some 
preliminaries and general Racket first!

Thank you,
Adrian

Hi! Sorry, I only get this list as a digest, so I didn't see your message 
until this morning. The code in the paper is not complete, and the paper 
isn't written so that a beginner in Racket could easily extract a working 
program from it. When I teach students this material, I give them a working 
starter file, and I will send that to you by private email, where we can 
also continue to discuss as needed.

I am at this moment working on converting my course materials on this topic 
into a free online resource similar to the one I did for functional data 
structures. But this is not ready yet. I hope to finish it in the next few 
months and I will post here when it is ready. --PR
