Constraining the searches to javascript, http://www.google.com/codesearch?hl=en&lr=&q=Object.prototype.propertyIsEnumerable.call+lang:javascript&sbtn=Search shows 85 results whereas http://www.google.com/codesearch?hl=en&lr=&q=Object.prototype.hasOwnProperty.call+lang:javascript&sbtn=Search has 263. I will proceed to worry only about hasOwnProperty until someone objects. -- Cheers, --MarkM
