I guess one can think of Clojure as a very Scheme-affine Lisp. Which is not surprising since Scheme was a kind of distilled iteration of Common Lisp as a common denominator.

Are there any Schemes which are as "Batteries included" as Clojure with broad and deep library support? (I think Racket has quite good support!)

This is a wonderful answer!

I return to my main calling: figuring out why people use PLT scheme without an academic incentive. There must be an answer here somewhere....
