I've been experimenting with an 'evaluate up to cursor' mode for my PL project. I love evaluating self-contained snippets in Lisp, this generalises the idea. The interpreter remembers the arguments when you run tests, then can re-use them when you say 'eval up to here'. What do you think?

... 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.

TIL Tcl has a notion of 'safe interpreters', a mode where you can run untrusted code in a sandbox: https://www.tcl.tk/man/tcl8.4/TclCmd/safe.htm Not many programming languages have this, but it's way safer to include in the implementation than try to build as a userland library.
