I had fun participating in the google codejam using factor, and in 2012 I wasn't the only one ! https://www.go-hero.net/jam/12/languages/Factor

Too bad that google codejam limited the available languages starting from 2018..

Factor is a very impressive engineering accomplishment, the standard library has so many useful algorithms and data structures implemented, and almost all of it with very clean APIs and documentation.

That website is very broken now sadly, and appears to only have records going up to 2017. I can't find 2018.
