This is cool. I’m glad you guys are doing this and glad you are seeing some promise and success. I’ve enjoyed reading your updates, especially the technical ones. I wish you’d do one on whatever you’re doing for memory management in your particular python variant. GC in a tightly constrained environment is interesting.
