The requirements in utility/CopyConstructible.html are the same as those in 
the C++ standard. FWIW, I agree with you that the address-of operator should 
not be included, and I recently (last week) filed a defect report against it. 
Only time will tell, but I'd be in favor of removing this (IMHO, unnecessary) 
requirement from Boost's version of the concept.
