Daniel Barlow:
He contributed sblisp.lisp, a set of patches to make SBCL
play nicely with ILISP. (Those patches have since disappeared from the
SBCL distribution because ILISP has since been patched to play nicely
- with SBCL.) He also figured out how to get the CMU CL dynamic object

Douglas Crosher:
He continued to improve CMU CL after SBCL forked from it, creating
many patches which were directly applicable to SBCL. Notable examples
include fixes for various compiler bugs, and a generalization
of the type system's handling of the CONS type to allow ANSI-style
