The funny thing LLM's are amazingly good with writing in Zig. They could inspect stdlib source code to fix compatibility issues with newer compilers and quite prolific with idioms.

For example I got a working application with minimal prompt like "I need an X11 tray icon app showing battery charge level". BTW result: https://github.com/baverman/battray/

Now I'm trying to implement a full taskbar to replace bmpanel2. Results are very positive. I've got feature parity app in 1h with solid zig code.
