There are good references and snippets on the Cookbook: https://lispcookbook.github.io/cl-cookbook/ https://lispcookbook.github.io/cl-cookbook/ for libraries, see https://github.com/CodyReichert/awesome-cl https://github.com/CodyReichert/awesome-cl (and see the lparallel or lfarm libraries, channels, cl-gserver, the built-in SBCL threading functions, etc) Also note that CL is not purely functional, you can throw in FP or OOP or iterative code.
