--- Comment #6 from Jason Merrill <jason at gcc dot gnu.org> ---
It's not clear to me that this optimization should use the constexpr machinery;
as I commented on bug 4131.  If optimization turns the initialization of a
static variable into a simple matter of storing a constant value, it should go
one step further and turn that constant value into a constant initializer.
