+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
+ (CONS FOO BAR) types.

+Robert MacLachlan:
+ He has continued to answer questions about, and contribute fixes to,
+ the CMU CL project. Some of these fixes, especially for compiler
+ problems, has been invaluable to the CMU CL project and, by
+ porting, invaluable to the SBCL project as well.
