a note on Polymorphism in Rebol and Oz

I have put a page on Polymorphism in Rebol and Oz with some mention of Strongtalk at eclectic-pencil

It really does not do justice to the richness of Rebol and may presuppose some familiarity with Smalltalk. All are available as freeware on the web.

If you work in JavaScript or C# there will be a lot to interest you in the trio of Oz, Strongtalk and Rebol. TiScript, for example, is a JavaScript variant which rejects prototype-based in favor of simple modules.
If you are looking at the new languages coming available for .NET and VisualStudio and want to see multi-paradigm programming then Oz is the place to start.
If you find you don't quite get Oz and the whole Emacs thing, start with Rebol.
If you don't want another way to think about web programming, just an alternative to JavaScript+CSS+HTML+whatever, download the Curl RTE and IDE.
I had been almost sold on XUL + JavaScript or XAML + C# and then I took a look at both Rebol and Curl.
In the next few days I will post something on the beauty of "Quick" Tk in Oz. If you were ever taken with Logtalk+Prolog or Datalog+RDF you will appreciate td(...) and lr( ...) as td( lr( ... )) i.e. layout of widgets is top-down and left-right...
