Interesting, but the documentation makes it sound like you have to preemptively wrap all the code you think you might want to change in a special wrapper "call" function. If true that makes this a lot less appealing than existing solutions for other languages that can modify any function without special annotations.

This is less worse than it sounds. The stuff I need hot reloading for is less than 5% of the total code base. It is usually stuff that I can't debug (ie: API response). So I am back and forth re-compiling. If I can get hot-reloading for that, that's a 95% time improvement for me. I could live with re-compiling for the rest of the code.
