The DR is young, there hasn't been a meeting since. There weren't many objections to the proposed resolution, although it did seem strange to some that common_type<int&,int&>::type would be int and not int&. I am too new to the process to say more... (I guess the proposed resolution should make the one-argument version of common_type equivalent to decay, to be consistent)
