I'm having trouble finding the sentence in the standard that requires it -
14.6., p8 says that " The lookup of names dependent on the template parameters
is postponed until the actual template argument is known..." Can you point to a
section/paragraph that excludes the address-of  operator expression from the
rule above?

Thanks
