Interpreter

• Common Lisp implementation of the Bedroom programming language. Please note that the concrete character set deployed constitutes a dependency on the Common Lisp implementation; in corollary, Unicode support may or may not be a feature incorporated in the personal environment. The interpreter at hand has been developed and tested with Steel Bank Common Lisp (SBCL) version 1.1.4 as part of the Lisp Cabinet 0.3.5 bundle.
