arnesi is a collection of utilities written by Marco Baringer. It includes some ASDF-extensions.

The current long term maintenance branch of arnesi can be found at github This will be the future quicklisp version of arnesi and is where to report bugs.

Among many other things, arnesi provides pattern matching facilities: a fare-matcher style pattern matcher and "regular" list matcher. optima's CLiki page claims optima had superseded arnesi's pattern matcher.
