I still agree that silent-but-deadly string issue is problematic, but it seems like an edge case for Symbols. Yes, plenty of code concatenates strings and/or numbers to make an object key or an array index; but just like "[object Foo]42" or "undefined42", "Symbol(description)42" is a obvious mistake and has the same bad outcome as the preceding two. The exception sucks and silent strings suck. I don't know which sucks less ;) Rick
