Oh? Somehow I missed the replies. I'll see if I can find them.

Interesting, I'd forgotten about that issue. And I'm curious about
your solution:
| DontEnums = [
| 'constructor',
| 'toString',
| 'valueOf',
| 'toLocaleString',
| 'isPrototypeOf',
| 'propertyIsEnumerable',
| 'hasOwnProperty'
| ];
Is that list sufficient? It seems suspiciously small. But I don't
have additional candidates right now.
Thanks for the response,
