An excellent Common Lisp implementation. It is fairly unique, in that it is written in Common Lisp, and it can bootstrap from an existing SBCL binary or from other Common Lisp implementations which are not written in Common Lisp (e.g. CLISP, ECL). This enables the SBCL devs to leverage the power/flexbility of Common Lisp in the process of implementing the language itself -- meta-programming at it's most elegant.
SBCL produces native machine code, which puts it among the fastest high level language implementations available. On many benchmarks, SBCL is faster than Java, which is surprising considering Java has a huge corporation behind it, whereas SBCL has a volunteer team behind it.
