Played more with the programming problems from Exercism. One of the exercises I did was the Hamming Exercise in Scheme. Its the first iteration and I might try to optimize it based on reviewing some of the other examples but I'm pretty pleased with how Exercism works. Part of that is because I can use my own tools in order to see how things work.
I'm still trying to figure out how to debug Guile code. I'd love to figure out how to step through code in Guile like I can in Python.
