Try Racket and DrRacket.
Racket continues to improve. I would love to see more energy put into making it viable as a commercial application development system.
From what I learn from reading about Racket from people in this forum. It's supposed to be a language to develop other languages. The other uses are to teach introductory programming classes. It's not designed to be a full fledged production grade programming language.
They also seem to be working on discarding the Lisp syntax entirely and making a new language out of Racket with a new syntax called 'Honu'. The project name is Rhombus/Racket2.
