Oh, this by Robert Strandh, whose also writing SICL, a very cool, modular implementation of Common Lisp in Common Lisp for bootstrapping. The idea is that other implementations of Common Lisp in Common Lisp can take modules from SICL. Already Christian Schafmeister's Clasp, another very interesting implementation of Common Lisp (using LLVM and made for easy interop with C++) uses parts of SICL, particularly the compilation framework Cleavir.
