--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Though it is static and what you're talking about is making automatic into
static. So guess we would need automatic temporary with something like { 1, 2,
3 } initializer and have reference bind to that temporary.
My C++-fu is limited.
