The DEFINER library adds a simple macro DEF to Common Lisp that replaces the various 'def*' forms in the language. It is a simple hack, but it adds some elegance to the language. Of course, it comes with its own way to be extended.
A NOTE ON FORKING
Of course you are free to fork the project subject to the current licensing scheme. However, before you do so, I ask you to consider plain old "cooperation" by asking me to become a developer. It helps keeping the entropy level at an acceptable level.
