This is a copy of the original tiny-clos downloaded from the Xerox PARC website. The announcement by Gregor Kiczales in tiny-announce.text was posted on the newsgroups comp.lang.scheme, comp.object, comp.lang.lisp and comp.lang.clos on December 2, 1992. Message-ID: Also of interest is the Swindle module tiny-clos, a heavily hacked derivative of the Xerox code produced by Eli Barzalay, "fitted to MzScheme, optimized and extended." The Chicken code seems to be based on that--it includes some comments and code introduced by Barzilay. http://barzilay.org/Swindle/swindle/tiny-clos.ss For further details, see trac ticket #32 http://www.irp.oist.jp/trac/chicken/ticket/32
