> At least half of my programming is tying together high level services and libraries. I know how I can express those concepts succinctly in Java, C++, JS, Swift etc. I'd love to see some examples of Lisp for something like a REST controller, where I call services, repositories etc. You should look at Racket. Racket is a Scheme-like[0] Lisp that aims to be "batteries-included". It includes things like a web-server out-of-the-box. [0] it is technically a hybrid of R5RS and R6RS, so pedants can argue over whether it is really "a Scheme" or not.
