I think Cane would really shine as an interactive language for live-coding music rather than purely as an AOT music language.

I think the best way to implement this would be to use the inotify subsystem from Linux to watch for file changes and reload the currently playing sequence when it finishes.

If no changes are made by the time the sequence terminates, it should loop until changes are made.

I'm not sure of a good solution for Windows here, maybe it has something similar to inotify we can use?

I like the idea of this being something that just works with your main editor with Cane running in the background. I'm not confident of my skills to write a decent REPL so why not let the user decide for themselves?
