--- Comment #5 from TC <rs2740 at gmail dot com> --- (In reply to Jakub Jelinek from comment #4) > Apparently what changed in C++11 is that it allows static > data members in unions and those clearly can have reference type, so that is > the reason why the restriction has been removed and nothing added the > restriction that non-static data members still may not have reference type. ...I quoted the part of the standard that says this is ill-formed in comment #3?
