It definitely isn't - the case cited is much clearer than the one in the article. 
Further, ADL *is* working correctly on the same operator and the same types in a 
different context.
Herb Sutter may or may not know that bug, however, it might not be appropriate for 
him to publicly highlight bugs of his employer's product.

You wanted to know situations where ADL fails to work with VC8 -- well, here is 
one. Analyse the code if you have to see it with your own eyes ;-).
