Subject: Should Win32Ole automatically support enumerable collections?

Here's some code i've written to work with the COM interface to Internet 
Explorer. It uses WIN32OLE.

def form # block
   forms = $iec.document.forms
   forms.extend( Enumerable )
   form = forms.find{ |f| yield f }
   form ? IEDomFormWrapper.new( form ) : nil
end

I originally expected this code to work without the call to forms.extend. 
Since forms is a COM collection object, it supports "each", and i figured 
Enumerable should be mixed in automatically. I think it was Chad Fowler who 
explained how i could do this myself -- or maybe it was Nathaniel Talbot.

This still seems like a workaround, however. I would be interested to other 
opinions on this matter.

In Visual Basic, for example, you can use any of the built in interation 
operators on COM Collections. The difference is that Ruby has a lot more 
"iteration operators".
