Racket (https://racket-lang.org) has an IDE (DrRacket) which isn't EMACS. ARC (which powers hacker news) is (was?) written in Racket. - Source: Hacker News / 6 months ago

I signed up for RacketCon, joining remotely. I am looking forward to it a lot. Usually I use the Racket language perhaps for 10% of my personal projects, but I am currently writing a Racket AI book, so all things Racket are of current interest. Past RacketCons have been a lot of fun. I usually use Common Lisp, but Racket is batteries included Scheme, and more, and is a very pleasant language and ecosystem.

Still, there are many useful tools based on these ideas, used by programmers and mathematicians alike. What you describe sounds rather like Datalog (e.g. Soufflé Datalog), where you supply some rules and an initial fact, and the system repeatedly expands out the set of facts until nothing new can be derived. (This has to be finite, if you want to get anywhere.) In Prolog (e.g. SWI Prolog) you also supply a set of... Source: 10 months ago

Haskell and Agda are probably the most obvious examples. Ocaml too, but it is much older, so its type system is not as categorical. There is also Idris, which is not as well-known but is very cool. Source: 10 months ago

Coq, Agda, Lean, Isabelle, and probably some others which are not coming to my mind at the moment, but those would be considered the major ones. Source: over 1 year ago

Safer doesn't mean better. You could proof program correctness, and get proven program with tools like Coq (https://news.ycombinator.com/) and Agda (https://wiki.portal.chalmers.se/agda/pmwiki.php). However, it leads to much higher cost of creating software than both C++ and Rust. It's a trade-off. A great thing about Rust is that the safety costs very little compared to Coq and Agda.

At the most extreme level, you disappear into a meditative solitary retreat for a couple of years to seek enlightenment, and when you emerge you're no longer a programmer who writes programs, you're a theorist who proves theorems in Agda, and you have transcended above things that are tainted by the inherent evil of the material plane like "side effects" and "business needs" and "delivery timelines" and "could you...
