loop and format: The Seedy Underbelly of Lisp

Previously, we looked at the core of the Common Lisp language and admired its succinctness and elegance.

They may lack the beauty of the Lisp core, but they easily make up for it with their power. These parts of the language are a real delight for any budding Lisp hacker.

The extensions we’ll cover in this section, loop and format, place a strong emphasis on power over mathematical elegance.
