Compiler error messages is such a deep topic. Even in rustc, a mature compiler that invests effort in diagnostic quality, I find interesting issues every few months. (The majority have been fixed pretty quickly, so it's really rewarding to file issues.)

nREPL is a really interesting protocol for developer tools. It's extensible, but one of the basic operations is eval(). If your nREPL server doesn't support a given operation, you can just send an eval request to achieve the same result!

My 3.5yo is learning to use a mouse, and it's super interesting. He's mastered clicks and drags, but he hasn't yet figured out lifting up the mouse when run out of mouse pad. That's a tricky case where you deliberately break the relationship between mouse and cursor movement.
