RecordGrid RichText demo applet

Here is a running Curl example with my data entries in the Curl HELP browser ( yes, running code in the browser - edit, save, restore ... ) - this one with RichText edit and view in a RecordGrid widget.

Does your IDE offer anything close for an advanced web content language for browser and/or desktop or mobile app's ?

Curl versus prototype.js

Here is what the prototype.js site suggests:

var Person = Class.create({
  initialize: function(name) {
    this.name = name;
  },
  say: function(message) {
    return this.name + ': ' + message;
  }
});

var Pirate = Class.create(Person, {
  say: function($super, message) {
    return $super(message) + ', yarr!';
  }
});

Here is my Curl equivalent

{define-class public Person
  field public-get private-set name:String
  {method public {say msg:String}:String
    {return {String self.name, ": ", msg}}
  }
  {constructor {default name:String}
    set self.name = name
  }
}

{define-class public Pirate {inherits Person}
  {constructor {default name:String}
    {construct-super name}
  }
  {method public {say msg:String}:String
    {return {String {super.say msg}, ", yarr!"} }
  }
}

Now here is my naive test code:

{output {{Pirate "Long-John"}.say "ahoy matey"}}

and here is the output:
Long-John: ahoy matey, yarr!

Note the lack of sigil's, var's and strange parenthetical matings.
But Curl also has 3D graphics and 2D paths and db interfaces and an IDE ... and now generates Android app's. Oh ... and a debugging environment with graphical inspectors and color outline  and fill debug inspection highlighters ... and is almost Smalltalk-ish LISP.
And from the same DARPA project as WWW.  SCSK Curl  (formerly MIT Curl).
Did I mention multiple inheritance? Mix-in's ? Anonymous proc's? Async workers?
