Racket is a fun language. My university uses the bundled teaching languages for first year CS courses. Some people really hate it, and others silently like it.

HN is written in Arc, and Arc is (was?) written in Racket.

Lisp is its own meta-language, and Racket is even more meta. It's a language construction kit, essentially.

It was actually ported to a Common Lisp based implementation a while back.

And all of them agrees to never use it after university, which is quite telling.

It's a general purpouse language. Reusig an old comment, I used it for

* A bot to reply emails that uses IMAP, SMTP and web scrapping. (It's not 100% automatic. It replies only the easy cases and adds labels so I reply the tricky ones.)

* An program to cleanup Moodle backups that uses gzip and xml. I compiled it and send it to my coworkers. (The backups have too much info, so before restoring it in another site it's better to remove the unused parts.)

Agree? Or maybe none of them graduate into a role where they get to decide what language to use?
