Lisp as a procedural language?

Someone at the PostgreSQL West conference last weekend expressed an
interest in a Lisp procedural language. The only two Lisp environments
I've found so far that aren't GPL are Steel Bank Common Lisp (MIT,
http://sbcl.sourceforge.net) and XLispStat (BSD,
http://www.stat.uiowa.edu/~luke/xls/xlsinfo/xlsinfo.html). SBCL is a
very active project, but I'm not sure about XLispStat.
