We will be meeting this Friday, November 4, for a special discussion on [E-Graphs](https://en.wikipedia.org/wiki/E-graph) and available Racket FFI provisions for Rust's [Egg](https://egraphs-good.github.io/) library. Oliver Flatt, who works on some of these things, has kindly agreed to attend and share his experiences with these technologies as they are used in the [Herbie](https://github.com/herbie-fp/herbie/tree/main/egg-herbie) library.

[Meeting notes](https://github.com/countvajhula/qi/wiki/Meeting-Notes) so far.

The topic is not Qi-specific, except that the context of understanding these things is towards potentially using these technologies in the Qi compiler.

All welcome, see you then!
