I have added a new library on the main Joy page. It deals with context-free grammars (and hence also with regular expressions). There are two possible uses of...

... Just like lists in Lisp and Scheme, Joy's quotations can be used in place of structs. In fact quotations are far more powerfull and flexible than structs. ...
Hello, all, I downloaded and compiled the joy sources for Mac OS-X. The only trouble was with the gc (Boehm's, correct?): it didn't recognize Mac OS-X. This...

Thanks to Brent Kerby for his concatenative combinators article, really excellent. I was thinking: "unit" and "cat" are kind of like _dynamic_ equivalents of...

... Correct -- Joy has polymorphic words. Joy itself isn't polymorphic, but rather provides RTTI and the ability to branch on that information. It's not...
