Except for ELisp... For some reason, it annoyed me so much that I couldn't stop writing in it. First, it was simple config tweaks, then small patches, and before I knew it, I was enjoying it. I ended up creating a few packages, and of course, with each one, I’d hit a new problem, push the old one aside, and start fresh. Just hoping I don’t forget to go back to it later. Well, I didn't and I'm slowly revisiting, refactoring or adding new things where necessary.
It works for what I need. Maybe you will find it useful too :)
