Thanks for the response, Igor.  My problem is that the JSNewEnumerateOp 
stuff allows spidermonkey to transparently perform 'for(p in o)'.  As 
far as I can tell, to use Scriptable.getIds() I would have to root out 
everywhere 'for(p in o)' was used in 1900 application files and change 
it to call getIds() and loop through the resulting array.  What I was 
hoping for was a way to make rhino treat 'for(p in o)' the way it can be 
treated in spidermonkey.
