Abstract
We report on our progress implementing a metaobject protocol for Common Lisp method combinations. This work was started in 2018 with a first implementation in SBCL, and then refined in 2023. Since then, we have two additional working implementations: one for ABCL and another for ECL. This paper describes the aforementioned ports, as well as a couple of refinements that were added since 2023.
