Extensible Streams
******************

SBCL supports Gray streams, user-overloadable CLOS classes whose instances can be used as Lisp streams (e.g. passed as the first argument to format).  Additionally, the bundled contrib module sb-simple-streams implements a subset of the Franz Allegro simple-streams proposal.
