@jimbokun "I've been using Clojure to "sketch" solutions for a Java project," and "When I switch back to Java, on the other hand, I feel like I'm chiseling my code in granite." remind me of this bit from SICP

"Pascal is for building pyramids -- imposing, breathtaking, static structures built by armies pushing heavy blocks into place. Lisp is for building organisms -- imposing, breathtaking, dynamic structures built by squads fitting fluctuating myriads of simpler organisms into place."

It seems that some things never change!
