As noted in another post, this is how some languages were basically designed to be used. I'll challenge that you can't just claim it is lisp. Common lisp, though, is a solid model for this method of development.
Yes it does feel like Smalltalk and Scheme. I never really liked Lisp (I feel like a heretic saying that on HN) but having this for Python of JavaScript would be infinitely more useful to me.
I would be curious to hear why. Where I work currently is full stack Clojure and I love it but have a few gripes (refactoring can be a pain) but overall it feels like a huge boon.
