Subject: Some ActiveRuby/RubyScript questions

Greetings!

I'm trying to convert some code from JScript to RubyScript to take 
advantage of the Ruby iterators, but found some problems with things 
behaving differently in JScript and VBScript compared to RubyScript.

Can someone please explain to me how you list the children of an object, 
corresponding to JScript:
   var a=[];
   for(var i in window)a.push(i);
So that a is an array containing the names of the children of the object 
(window in the example, but it might be anything.)

Also, I'd like to know how to detect whether a property of an object exists 
or not, something of the kind:
   if(typeof document.all!='undefined'){/* some action or other... */}


TIA,
