Clozure (http://ccl.clozure.com/ http://ccl.clozure.com/) is good at being better than SBCL in some areas (like, its compiler is a lot simpler). But there's room for the current CL implementations. CLISP for example is the only Common Lisp implementation doing JIT compilation. ABCL deploys on the JVM. It would be nice to have a CL deploy to JavaScript. And really nice to have a new JITed implementation that takes ideas from LuaJIT. Don't forget the commercial CL implementations. Lispworks is pretty awesome. What's really needed is to treat Common Lisp as a platform like the JVM. And for that to happen the current Free Software system libraries (networking, I/O, threading, Quicklisp, ASDF, FFI) need to continue to be improved, and need to run well on all CL implementations.
