Just a suggestion. Is it possible to make a self-bootstrappable libcl so tiny that it can be distributed with implementations?
What I mean is the possibility of adding an option --with-libcl to a configuration process that, starting from a simple set of scripts/lisp files/makefiles, downloads and installs the appropriate support for this set of libraries, perfectly integrated with the implementation that requested them.
Dunno, maybe it is just a stupid idea :-)
