I'm adding a += operator to my programming language, because writing `x = x + 1` is tedious. This opens the tricky design question of which operators should support this. Is += and -= sufficient, or do you expect things like >>= and **= to be available?

... and my third refactoring with Cursor changed some function calls that I didn't want it to modify. Subtle. I've had the most success with AI coding tools when I know exactly what I want the output to look like.

I'm implementing an interpreter, and wondering how often I should check for interruptions (e.g. Ctrl-C). I don't want to spend too much CPU time checking whether I've been interrupted, but I also want slow programs to stop promptly. It's tricky.
