Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

(ns clipboard.core
  (:require [fipp.edn :as fipp])
  (:import (java.awt.datatransfer DataFlavor Transferable StringSelection)
           (java.awt Toolkit)
           (java.io StringWriter))
           
(defn get-clipboard
  "get system clipboard"
  []
  (-> (Toolkit/getDefaultToolkit)

(ns com-widdindustries-statsatom
  "A drop-in replacement for clojure.core/atom
  
  The difference is that this record the following stats, held in the atom's metadata:
   - number of times updated via swap!/swap-vals! and 
   - number of attempts made to do those updates
  
  Clearly these stats themselves need to be atomically updated so there's some overhead added there.

Developer experience, libraries, performance… (2021/11)

I'll preface this with three things. 1. I prefer schemes over Common Lisps, and I prefer Racket of the Schemes. 2. There is more to it than the points I raise here. 3. I assume you have no previous experience with Lisp, and don't have a preference for Schemes over Common Lisp. With all that out of the way... I would say Common Lisp/SBCL. Let me explain

1. SBCL Is by far the most common of the CL implementations in 2021. It will be the easiest to find help for, easiest to find videos about, and many major open source CL projects are written using SBCL
2. Download a binary directly from the website http://www.sbcl.org/platform-table.html (even for M1 macs) to get up and running (easy to get started)
3. Great video for setting up Emacs + Slime + Quick Lisp https://www.youtube.com/watch?v=VnWVu8VVDbI

Now as to why Common Lisp over Scheme
