"Lisp is as esoteric as it is powerful and coding is
truly the only route to mastering the intricacies of this complex
and supremely intriguing language and the rapid development model
presented by its REPL (Read Eval Print Loop) or top-level. Lisp
masters well earn the title of wizards, and it's no coincidence
that Abelson and Sussman refer to casting spells with Lisp, a
common metaphor within the community and modified title of a
popular beginner's tutorial at lisperati.com."
