--- Comment #21 from Iain Sandoe <iains at gcc dot gnu.org> --- Avi, If we are agreed that there is no GCC bug here (the change from pointer to reference is already in the queue) I would suggest that new design discussion would be better by putting a paper or suggestions to the WG21 evolution list (and certainly involving folks who are not present 'here'). In which case the bug could be closed.
